✅ CHINT 186759 – G Eb 4P C63 4.5kA Detailed Description Description The CHINT eB Series miniature circuit breaker (MCB), part number CHINT 186759, is a 4-pole (4P) high-capacity protection device rated at 63A, featuring a C tripping curve. It is specifically designed to protect three-phase + neutral circuits from overloads and short circuits in demanding residential, commercial, and light industrial environments. With a 4.5kA short-circuit breaking capacity, this breaker is ideal for circuits that feed large equipment such as central HVAC systems, industrial pumps, or high-power distribution panels. It operates at 50/60Hz and complies with IEC 60898 standards. A thermal-magnetic trip unit enables fast, accurate response to electrical faults, while a positive contact indication allows for visual confirmation of the breaker’s status. The device is DIN rail mountable and compact in design, supporting clean and efficient installation in modern electrical systems.
