Why Choose the ABB 2CDS381001R0278 Miniature Circuit Breaker?
The ABB 2CDS381001R0278, also known as the S301P-Z2, is a premium single-pole miniature circuit breaker (MCB) from the ABB System pro M compact S300P series. It is designed to provide dependable protection against overloads and short circuits in industrial electrical installations where highly sensitive electronic equipment requires extremely fast fault protection.
Featuring a Type Z tripping characteristic, the S301P-Z2 is specifically engineered for protecting PLCs, semiconductor devices, instrumentation, control circuits, measuring equipment and other sensitive electronic systems. Its very sensitive magnetic tripping characteristic rapidly disconnects low-level fault currents before damage can occur.
With a 2 A rated current, compact single-pole construction and a 25 kA rated short-circuit breaking capacity, the ABB 2CDS381001R0278 delivers exceptional circuit protection whilst occupying only one DIN module, making it ideal for industrial automation and control panels.
