Circuit & Load Protection

AB 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 Protection Circuit BreakersRead More

AB Circuit Breakers 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.

Electronic Circuit ProtectionRead More

AB Electroinic 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.

  • Allows less “let-through” energy than non-limiting circuit breakers
  • Uses output circuit indicators to indicate the presence of affected circuits for rapid troubleshooting and correction
  • Provides ON/OFF and reset buttons
  • Offers certified Class 2 circuits (on select devices only)
  • DIN Rail mountable

Motor Protection Circuit BreakersRead More
