✅ CHINT 186772 – G EBC 3P C63 3kA Description The CHINT G EBC 3P C63 3kA miniature circuit breaker (MCB) is built for the reliable protection of high-capacity three-phase electrical systems. With a rated current of 63 amperes and a C-curve tripping characteristic, it is ideal for heavy-duty industrial loads such as large motors, transformers, power distribution units, and machinery requiring moderate surge tolerance. It delivers a 3kA short-circuit breaking capacity and fully complies with IEC 60898 standards. The 3-pole design ensures full-phase isolation during faults, while DIN rail compatibility and screw clamp terminals allow quick and secure installation in commercial and industrial panels.
