Circuit Breakers and Circuit Protectors
Category Selection
Circuit breakers are re-settable electrical safety devices that protect equipment and processes from damage caused by overload or short circuits. Their purpose is to interrupt current flow to protect downstream equipment and prevent the risk of fire.
- Molded case circuit breakers: for branch and feeder circuit protection of large loads, up to 1200 A
- Miniature circuit breakers: DIN-rail mountable for branch circuit protection, up to 63 A
- Miniature supplementary protectors: for additional protection and disconnecting means where branch circuit protection is already provided
- Electronic circuit breakers/protectors: provide single- or multi-circuit supplementary protection from a single device
- Mini supplementary protectors for terminal blocks: provide space-saving, terminal block style UL 1077 supplementary protection
- Accessories for MCCBs and miniature and electronic circuit protectors

Molded Case Circuit Breakers (MCCB)
Molded case circuit breakers provide branch or feeder circuit protection against overload or short-circuits, with thermal-magnetic or adjustable electronic trip units. UL 489 rated MCCBs are available in various frame sizes for 2- or 3-pole configurations up to 1200A.
- Fuji BW Series, up to 800A
- 3P Series, up to 600A
- Gladiator GCB Series, up to 1200A
Miniature Circuit Breakers (MCB)
UL 489 DIN-rail mountable miniature circuit breakers protect feeder, branch, and control circuits from overload current. These Eaton FAZ-NA and Gladiator GMCBU series breakers offer reliable protection and are rated for AC or DC applications.
- 1-, 2- and 3-pole breakers
- B, C, and D trip curves
- Current ratings up to 63A
Miniature Supplementary Protectors
UL 1077 supplementary protectors provide additional overcurrent protection where branch protection is already provided or not required. Eaton FAZ Series and Gladiator GMCB Series DIN-rail mountable protectors save space and money.
- 1-, 2- and 3-pole breakers
- B, C, and D trip curves
- Current ratings up to 63A
Electronic Circuit Protection
Newest Additions!
- WAGO 787-3861 series single-channel electronic circuit breakers
Electronic circuit breakers/protectors provide supplementary protection of 12 or 24 VDC circuits for up to 10A per channel, protecting against overloads and short circuits. NEC Class 2 rated models allow conversion from a non-NEC class 2 power supply to a Class 2 device.
- Single- or multi-channel breakers/protectors in a compact form factor
- Fixed and adjustable current models available
- Modular protectors consist of individual protection modules that can be combined for flexible configurations and easy installation
Mini-Supplementary Protectors for Terminal Blocks
DINnector DN-FE series terminal blocks provide modular circuit protection using UL 1077 supplementary circuit protectors. DIN-rail mountable terminal block sockets are available with or without trip-indicating LEDs, with current ratings up to 10 A.
- DN-FE series sockets
- DN-SUPP-xx single-pole UL 1077 supplementary protectors
- DN-FESPA end covers
