2CCF019914R0001 ABB S804S-B1 1 A 4-Pole Type B MCB 50 kA

Why Choose the ABB S804S-B1 High Performance MCB?

The ABB S804S-B1 is a high-performance four-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding electrical installations. As part of the ABB S800S high-performance circuit breaker series, it combines robust construction with high fault-current interruption capability for commercial, industrial and electrical distribution applications.

This current-limiting circuit breaker features a Type B tripping characteristic, making it suitable for circuits with relatively low inrush currents. Its four-pole configuration provides coordinated switching and protection across four conductors, making it particularly useful for three-phase systems where four-pole circuit protection is required.

With a rated current of 1 A, a four-pole configuration and a 50 kA short-circuit breaking capacity, the S804S-B1 provides high-performance protection for low-current circuits where substantial prospective fault currents may occur. ABB order code 2CCF019914R0001 identifies this 1 A, four-pole Type B version of the S800S range.
