ABB S301P-Z32 single-pole miniature circuit breaker with 32 A rated current, Z tripping characteristic and 25 kA breaking capacity for protecting sensitive industrial electronic circuits.
£58.55
The ABB S301P-Z32 (2CDS381001R0538) is a premium single-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in industrial electrical installations. As part of the trusted ABB S300P series, it delivers a high 25 kA breaking capacity and is manufactured in accordance with international IEC and UL standards for demanding industrial applications.
The Z tripping characteristic is specifically engineered for protecting sensitive electronic equipment and control circuits requiring rapid magnetic tripping at comparatively low fault-current levels. This makes it ideal for PLCs, instrumentation, semiconductor equipment, communication systems and other precision industrial electronics.
With a 32 A rated current, compact DIN rail mounting and ABB's renowned reliability, the S301P-Z32 is an excellent choice for industrial control panels, OEM machinery, automation systems and commercial electrical installations where dependable circuit protection is essential.
Miniature circuit breakers automatically disconnect electrical circuits whenever overloads or short circuits occur, protecting equipment, wiring and connected systems from electrical damage. Unlike conventional fuses, MCBs can simply be reset after the fault has been rectified, reducing downtime and maintenance costs.
The ABB S301P-Z32 has been specifically developed for industrial installations where sensitive electronic equipment requires rapid magnetic tripping. Its Z characteristic provides fast fault isolation to help protect PLCs, instrumentation and precision control systems from damage.
