✅ CHINT 185488 – G EBC 4P C40 3kA Description The CHINT G EBC 4P C40 3kA miniature circuit breaker (MCB) provides advanced protection for four-pole systems in three-phase + neutral installations. Rated at 40A with a C-curve tripping characteristic, it is ideal for medium-to-heavy load circuits such as commercial air conditioning systems, balanced distribution boards, and sub-main feeders. This MCB delivers a 3kA short-circuit breaking capacity and meets IEC 60898 standards. Its four-pole design ensures simultaneous disconnection of all phases and neutral, enhancing both safety and system reliability. With DIN rail mounting and screw terminals, installation is fast, safe, and secure.
