£58.55
The ABB S301P-Z4 (2CDS381001R0338) is a premium single-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in industrial and commercial electrical installations. As part of the proven ABB S300P series, it delivers high breaking capacity and reliable operation for control panels, automation systems and power distribution equipment.
Manufactured to meet internationally recognised standards, the S301P-Z4 is particularly suited to protecting sensitive electrical and electronic equipment. Its Z tripping characteristic offers rapid magnetic tripping at relatively low fault currents, making it ideal for circuits with delicate components that require enhanced protection.
With a 4 A rated current, single-pole configuration and DIN rail mounting, this compact circuit breaker is an excellent choice for industrial machinery, instrumentation, control circuits and specialist electrical installations where fast fault detection is essential.
Miniature circuit breakers automatically disconnect the electrical supply when overloads or short circuits occur, helping protect wiring, equipment and connected devices from damage. The Z tripping characteristic responds rapidly to relatively low fault currents, making it particularly suitable for electronic equipment and precision control circuits.
ABB S300P circuit breakers are trusted by electrical engineers, panel builders and OEM manufacturers worldwide thanks to their high reliability, quality construction and compliance with international standards.
