ABB 2CDS274001R0634 S204M-C63 4P 63A 10kA C-Curve Miniature Circuit Breaker (MCB)

The ABB S204M-C63 (SKU: 2CDS274001R0634) is a 4-pole 63A miniature circuit breaker (MCB) from the S200M series, engineered for reliable overcurrent and short-circuit protection in industrial and commercial control panels. Rated at 230/400V AC with a 10kA breaking capacity and C-curve tripping characteristic, the S204M-C63 delivers robust performance for motor and general-purpose distribution circuits requiring higher magnetic trip thresholds.
