Circuit & Load Protection

Circuit and Load Protection products protect solenoids, relay coils, pilot devices, PLC outputs, and more. They are DIN Rail mountable for quick installation and excellent for high-density configurations. We offer electronic circuit protection modules, circuit breakers, and motor protectors including modular protection systems, bi-metallic or solid-state overload relays and surge protectors and filters.

Circuit Breakers

Circuit Breakers

Circuit breakers include industrial DIN Rail circuit breakers, 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.

Disconnect Switches

Disconnect Switches

Our Disconnect Switches are available in both fixed- and variable-depth styles with flange- or door-mounting styles. Our switches are NEMA, IEC, and UL rated. We offer a variety of fused and non-fused versions from 20...1250 A in both open and enclosed configurations.

Electronic Circuit Protection

Electronic Circuit Protection

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.
