Why Choose the ABB S304P-D32 Miniature Circuit Breaker?

The ABB S304P-D32 is a robust and high-performance miniature circuit breaker (MCB) designed to provide reliable protection against overloads and short circuits in industrial electrical installations. As part of the ABB System pro M compact S300P series, it combines high breaking capacity with dependable circuit protection for demanding electrical distribution applications.

This circuit breaker features a D tripping characteristic, making it suitable for circuits where higher short-duration inrush currents can occur. Its 4-pole configuration provides protection across four conductors without a neutral pole, while the compact modular design enables straightforward installation in distribution boards and control panels.

With a rated current of 32 A and a rated breaking capacity of 25 kA, the S304P-D32 provides dependable protection for industrial circuits requiring a high level of short-circuit interruption performance. Its DIN-rail mounting and compatibility with the System pro M compact accessory range simplify installation and system integration.
