ABB 2CDS381001R0404 S301P-C40 1P 40A 20kA C-Curve Miniature Circuit Breaker

The ABB S301P-C40 (SKU: 2CDS381001R0404) is a high-performance 1-pole 40 A miniature circuit breaker (MCB) from the S300P series, engineered for reliable overcurrent and short-circuit protection in industrial control panels and commercial electrical installations. With a breaking capacity of 20 kA and C-curve tripping characteristic, the S301P-C40 is suited for protecting circuits with moderate inrush currents, including motor feeders, lighting circuits, and general distribution boards. Its compact 17.5 mm width optimises DIN rail space in high-density switchgear assemblies.
