£48.26
The ABB S301P-C50 (2CDS381001R0504) is a high-performance single-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in demanding industrial electrical installations. As part of the trusted ABB System pro M compact S300P series, it delivers exceptional reliability, a high breaking capacity and compliance with international IEC and UL standards for industrial applications.
Featuring a C tripping characteristic, the S301P-C50 is ideal for protecting general-purpose industrial and commercial electrical circuits with moderate inrush currents, including lighting, socket outlets, distribution circuits and control equipment. Its thermal and magnetic trip mechanisms provide fast and reliable protection whilst reducing nuisance tripping during normal operation.
With a 50 A rated current, single-pole configuration and DIN rail mounting, this miniature circuit breaker is perfectly suited to industrial control panels, machinery, OEM equipment and commercial electrical distribution systems requiring dependable circuit protection.
Miniature circuit breakers automatically disconnect electrical circuits whenever overloads or short circuits occur, helping protect wiring, machinery and connected equipment from electrical damage. Their resettable design enables systems to be quickly restored once faults have been safely rectified.
The C tripping characteristic is the most widely specified curve for general-purpose installations, making it suitable for distribution circuits, lighting, socket outlets, commercial equipment and industrial control systems with moderate inrush currents.
