£54.10
The ABB S301P-Z25 (2CDS381001R0518) is a premium single-pole miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in industrial and commercial electrical installations. As part of the proven ABB System pro M compact S300P series, it offers a high 25 kA breaking capacity and is manufactured in accordance with recognised IEC and UL standards for demanding applications.
Featuring a Z tripping characteristic, the S301P-Z25 is specifically engineered to protect sensitive electronic equipment where rapid magnetic tripping is required. It is ideally suited to PLCs, instrumentation, semiconductor equipment, communication systems and precision industrial control circuits that require enhanced protection against fault currents.
With a 25 A rated current, single-pole configuration and DIN rail mounting, this miniature circuit breaker is an excellent choice for OEM machinery, industrial automation, electrical control panels and commercial distribution boards where dependable circuit protection is essential.
Miniature circuit breakers automatically disconnect electrical circuits whenever overloads or short circuits occur, helping protect wiring, electronic equipment and connected systems from costly damage. Unlike traditional fuses, they can be reset after a fault has been cleared, reducing maintenance time and improving system availability.
The Z tripping characteristic provides very rapid magnetic tripping at comparatively low fault-current levels, making it particularly suitable for protecting PLCs, instrumentation, communication systems and other sensitive electronic equipment where fast fault isolation is critical.
