£51.88
The ABB S301P-Z20 (2CDS381001R0488) is a premium single-pole miniature circuit breaker (MCB) engineered to provide reliable protection against overloads and short circuits in demanding industrial electrical installations. As part of the trusted ABB System pro M compact S300P series, it combines exceptional breaking capacity with fast fault detection, making it ideal for protecting sensitive electronic equipment and industrial control systems.
Featuring a Z tripping characteristic, the S301P-Z20 is specifically designed for applications requiring rapid magnetic tripping at comparatively low fault-current levels. This makes it particularly suitable for PLCs, instrumentation, semiconductor equipment, communication systems and other sensitive electronic circuits where fast disconnection helps prevent equipment damage.
With a 20 A rated current, single-pole configuration and DIN rail mounting, this miniature circuit breaker is ideally suited to industrial control panels, OEM machinery, automation systems and commercial electrical installations requiring dependable circuit protection.
Miniature circuit breakers automatically disconnect electrical circuits whenever overloads or short circuits occur, helping protect wiring, industrial machinery and connected equipment from electrical damage. Their resettable design enables systems to be quickly restored once the fault has been rectified.
The Z tripping characteristic is intended for circuits containing sensitive electronic equipment where very fast magnetic tripping is required. It is commonly specified for PLC systems, instrumentation, semiconductor equipment and industrial automation controls where equipment protection is critical.
