Why Choose the ABB S304P-Z3 Miniature Circuit Breaker?
The ABB S304P-Z3 is a compact and high-performance miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in industrial and electrical distribution systems. As part of the ABB System pro M compact S300P series, it combines high breaking capacity with practical DIN-rail installation for professional low-voltage applications.
This circuit breaker features a Z tripping characteristic, providing sensitive protection for circuits containing electronic equipment and components requiring lower fault-current thresholds. The 4-pole configuration provides four protected poles without a neutral pole, making the device suitable for multi-pole AC circuit protection where a switched neutral is not required.
With a rated current of 3 A, a 25 kA rated breaking capacity and an AC supply, the S304P-Z3 is suited to sensitive industrial control circuits, automation systems and electrical distribution applications where dependable circuit protection and compact panel integration are required.
