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.
UL 489 DIN-rail mountable miniature circuit breakers protect feeder, branch, and control circuits from overload current. Rated for AC or DC applications, these Eaton FAZ-NA series and Gladiator GMCBU series breakers offer reliable protection.
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.
Electronic circuit breakers provide supplementary circuit protection of 24 VDC circuits, 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.
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, in current ratings up to 10 A.
Accessories for molded case circuit breakers include rotary handles, flexible handles, flange handles, auxiliary contacts, undervoltage release, shunt trip, six-wire connector, as well as mounting and installation hardware and replacement lug kits. Available for the following brands:
Accessories for miniature and electronic circuit breakers include auxiliary switches, alarm switches, shunt trip release switches, lockout attachments to prevent unauthorized activation, busbar systems to connect circuit breakers, busbar shrouds, and wiring lugs. Various items are available for:
