ABB S804P-C125 four-pole high performance miniature circuit breaker with a 125 A current rating, C characteristic and short-circuit breaking capacity of up to 50 kA for industrial electrical protection.
£524.53
The ABB S804P-C125 is a robust four-pole high performance miniature circuit breaker (MCB) designed to protect demanding industrial and commercial electrical installations against overloads and short circuits. Part of the advanced ABB S800P circuit breaker series, it combines a high rated current with exceptional fault interruption performance.
This circuit breaker features a C tripping characteristic, making it suitable for circuits containing equipment with moderate inrush currents. Its dependable thermal-magnetic protection helps safeguard cables, machinery and electrical distribution equipment while reducing the risk of damage caused by abnormal current conditions.
With a rated current of 125 A, a four-pole configuration and an ultimate short-circuit breaking capacity of up to 50 kA at 240/415 V AC, the S804P-C125 is ideal for high-demand power distribution, industrial switchboards and machine control systems. Its compact rail-mounted construction enables straightforward integration into professional electrical panels.
The ABB S804P-C125 continuously monitors current flowing through an electrical circuit and disconnects the supply when an overload or short circuit occurs. Its thermal element provides overload protection, while its magnetic release responds rapidly to severe fault currents.
The S800P series is engineered for installations where conventional miniature circuit breakers may not provide sufficient current capacity or fault interruption performance. Its four-pole design enables simultaneous isolation of all conductors in compatible three-phase systems, supporting safe maintenance and dependable circuit protection.
