✅ CHINT 186771 – G EBC 4P C63 3kA Description The CHINT G EBC 4P C63 3kA miniature circuit breaker (MCB) offers high-capacity protection for three-phase + neutral systems in commercial and industrial applications. With a 63A current rating and C-curve tripping characteristic, it is ideal for protecting large balanced loads such as sub-distribution panels, machinery, HVAC equipment, and industrial power circuits. It provides a 3kA short-circuit breaking capacity and complies with IEC 60898 standards. The four-pole design ensures simultaneous disconnection of all three phases and the neutral for maximum safety. With DIN rail compatibility and screw clamp terminals, this MCB guarantees secure, easy installation and long-term durability.
