Area of Application The temperature detector P is used wherever protection against overtemperatures is required. Specific applications include: protection of primary windings in transformers, winding protection in small electric motors and general temperature protection of small electric equipments. Function The temperature detector P operates independent from any current supply. Temperature detection is effected by means of a bimetal disk which was first dimensioned in accordance with the required cut-off temperature TA. When this fixed cut-off temperature TA is reached, this bimetal disk  will snaps over, breaking a contact system and thereby interrupting the electric circuit of the device to be protected. After cooling down and reaching the cut-in temperature TE, the bimetal disk will automatically return into its original position and thus re-make the contact. The electric circuit is closed again.

Area of Application The thermo switch O is used whenever switch-on function is needed, caused by overheating or increasing temperature. Specific applications include: cooling fan, alarm signal, controller, timer. Function The thermo switch O operates not current sensitive. Temperature detection is realized by a bimetal snapdisk. When the switch-on temperature TE is reached, the bimetal disk will snap over to close a contact system. After cooling down and reaching the cut-off temperature TA, the bimetal disk will automatically return to its initial position and open the contacts again. Products > Products > Thermal Protector BM1   Data sheet Field of Application The thermal overload protector type BM-1 is an electromechanical safety device, which provides complete protection to your electrical equipments against over-heating and over-loading and mechanical malfunctions.

Typical Applications To protect household equipment, electrical motors, transformers, electrical ballast, etc.   Products > Products > Thermal motor protector TM1   data sheet Field of application 1. The thermal motor protector TM1 is an electro-mechanical safety device, which provides complete protection to your electrical equipments against overheating and overloading and mechanical malfunctions. The contacts close again automatically, as the device cools down. 2. Because of the very small size and high compressive strength it specially can be used for direct fitting in coils of motors and transformers. 3. The thermal motor protector TM1 is single pole and operates independent from any current supply. Contact configuration has two modes: normally closed (NC) or normally open (NO). Applications Motor for fan and air conditioner, motor of washer, motor of oil and smoke pumping, transformers, ballast of fluorescent light, electromagnetism and microwave stove, etc. Products > Products > Temperature Limiter Q   Data sheet Data sheet Mounting bracket 506005 Data sheet Mounting bracket 506000-506003 Data sheet U-clip 506100 Data sheet U-clip 506101 Holding resistor-table Area of Application The temperature limiter Q  is used wherever, on the one hand, protection against  overtemperatures is required, and, on the other hand, automatic cut-in of the device to be protected - subsequent to a follow-on cooling down period - is undesirable or not permissible.   Function The temperature limiter Q operates independent from any current supply. Temperature detection is effected by means of a bimetal disk which was first dimensioned in accordance with the required cut-off temperature. When this fixed cut-off temperature TA is reached, this bimetal disk will snap over, breaking a contact system and thereby interrupting the electric circuit of the device to be protected. In order to prevent any automatic cut-in of the circuit when the switch cools down again, the switch is equipped with an electric latch/self-holding device. Self-holding Function: By means of a resistor heat is generated by the supply voltage applied after breaking the contact. This heat prevents any decrease in temperature below the value necessary for the cut-in temperature TE. In this was, the switch will keep its contact open, irrespective of its ambient temperature. To close the contacts of the switch, and thus closing the current circuit, will be possible only after disconnection from the power supply .

Function The current and temperature limiter  Y operates current sensitiv. Temperature detection is realized by bimetal disk which was first dimensioned in accordance with the required cut-off temperature. When this fixed cut-off temperature TA is reached, this bimetal disk will snap , breaking a contact system and thereby interrupting the electric circuit of the device to be protected. Current sensitivity In the case of an obvious current increase (blocking current or short-circuit current) a resistor, lying in series with the contact system inside the limiter, heats the bimetal disk to its cut-off temperature TA very quickly. When this cut-off temperature TA is reached, the bimetal disk will snaps suddenly and breaks the contacts of the switch. To get an optimal adjustment in accordance to the application there are wide range of resistor values are available . Self-holding function By means of a resistor heat is generated by the supply voltage applied after breaking the contact. This heat prevents any decrease in temperature below the value necessary for the cut-in temperature TE. In this was, the switch will keep its contact open, irrespective of its ambient temperature. Cut-in of the switch, and thus closing the circuit, will be possible only after disconnection from the supply voltage. Products > Products > Temperature Switch Controller/Limiter   Data sheet   By means of a resistor heat is generated by the supply voltage applied after breaking the contact. This heat prevents any decrease in temperature below the value necessary for the cut-in temperature TE. In this was, the switch will keep its contact open, irrespective of its ambient temperature. Cut-in of the switch, and thus closing the circuit, will be possible only after disconnection from the supply voltage.   Thermo switches only react when external thermal heating affects them. The thermal coupling to the source of heat is effected by means of a bimetal disk lying directly below the metallic covering cap.   Due to small size, high reliability, independence of location and the fact that it is totally maintenance-free,  a thermo switch is the ideal instrument for perfect thermal protection. Types of Contacts/Contact Types KO - break contact which will automatically return into its original position. KS - make contact which will automatically return into its original position. KB - limiter with mechanical latch/self-holding SB - break contact with electric latch/self-holding   Products > Products > High Temperature Protector TB97   Data sheet Area of Application If thermal overload protection in is demand: simple in function, reliable in technology and competitive in price, take the overload protector TB97. The TB97 is based on reliable bimetal snap-disc technology and especially designed for application when high operating temperatures (from 200°C up to 450°C) are required. Even if the operating temperature is higher than 400°C the tolerance is within ± 15K. Typical applications are: electrical oven, heating plates, barbeque equipments, industrial usage like welding machines and soldering machines. Description When the ambient temperature rises and will reach the fixed operating (snap disc) temperature , the protector cuts out ( normally closed type) or close (normally open type ) the electrical circuit. After cooling down, the contacts are going back to their original position automatically (automatic reset function). Within nominal power conditions the protector TB97 works independent from any current value. housing dimension: length 27,5mm x width 15,5mm x height 12,5mm    Products > Products > Thermal protector TB02/TB05   Data sheet TB02 Data sheet TB05 Area of application Thermal protector TB02/TB05-type will be used to protect against a thermal overheating of small electric applications.

Typical applications are time delayed turnoffs of fans ventilating bath rooms or ovens to remove water condensation. Function If control voltage is applied to the control leads, the working contact closes time delayed. This contact system is galvanic separated from the control leads. After removing control voltage the contact keeps closed for another delayed time which depends on surround temperature and the time control voltage was present. Products > Products > Insulating Sleeving   Data sheet   Thinking of a hose may already lead to philosophical ideas: in one direction, the endless emptiness prepared to take in whatever conducts analog and digital electric impulses. All round, the wrapping armed with various active substances, thin and flexible but resistant to such an extent that it keeps off any external influences and preserves the mystery of the signals flowing through it.   With this philosophical contemplation, we already pointed out the most important tasks of our insulating hoses: elctrical, mechanical and thermal protection of electric lines in vehicles, machines and the industrial area as well as in windings transformators, motors and household appliances.
