Circuit and Load Protection Circuit Breakers include industrial DIN Rail circuit breakers, fuse holders, high density miniature circuit breakers, circuit protectors, residual current devices, miniature circuit breakers and supplementary protection. We offer many configurations, voltage ranges and current ranges to meet your requirements.

• 1692 Electronic Circuit Protection Module

Our electronic circuit protection modules provide the preferred solid-state protection for secondary circuits of switched mode power supplies. Faster than the self-protection of the power supply, they are designed to accommodate inductive and capacitance loads, avoiding nuisance tripping. When they do trip, an indicator shows which of four circuits caused the fault, saving troubleshooting time.

• 140M IEC Circuit Breakers

Motor Protection Circuit Breakers include molded-case circuit breakers and rotary circuit breaker operating mechanisms. We offer five different IEC-only frame styles and eight UL and IEC frame styles. You can choose from thermal-magnetic or electronic circuit breakers.

• 1492-SP Miniature Circuit Breakers

Bulletin 1492-SP Energy Limiting Supplementary Protector/Miniature Circuit Breakers protect equipment, systems, and cables by means of a quick disconnection. These devices protect energy loads such as controller I/O, solenoids, power supplies and control transformers from the damages of power surges. We offer a wide range of currents and trip characteristics so you can choose the appropriate level of protection for your application.
