£105.27
The ABB 2CDS381103R0518, designated S301P-Z25NA, is a high-performance miniature circuit breaker (MCB) from the ABB System pro M Compact S300P series. Designed for specialist industrial and commercial applications, it provides dependable protection against overloads and short circuits whilst offering an extremely sensitive Type Z tripping characteristic for circuits supplying delicate electronic equipment and semiconductor devices.
Manufactured to recognised IEC and UL standards, the ABB S301P-Z25NA combines a compact DIN rail-mounted design with a high short-circuit breaking capacity, fail-safe terminals and clear switching indication. Its robust construction makes installation and long-term maintenance straightforward in industrial control panels and distribution systems.
Featuring a 25 A rated current, a Type Z tripping characteristic, a 1P+N configuration and a 25 kA breaking capacity, the ABB 2CDS381103R0518 is ideally suited to protecting highly sensitive electronic circuits where rapid fault disconnection is essential.
Type Z miniature circuit breakers provide one of the fastest magnetic tripping characteristics available, making them particularly suitable for protecting semiconductor devices, PLCs, measurement equipment, electronic power supplies and other sensitive electrical loads. Their rapid response helps minimise damage caused by fault currents whilst maintaining dependable overload protection.
The ABB S301P-Z25NA combines this enhanced sensitivity with ABB's proven S300P platform, delivering high interruption performance, long service life and reliable protection for specialist industrial control applications.
