Why Choose the ABB S804U-K15 High Performance MCB?
The ABB S804U-K15 is a high-performance 4-pole miniature circuit breaker (MCB) designed to provide reliable overload and short-circuit protection in demanding industrial and commercial electrical systems. As part of the ABB S800U high-performance MCB series, it combines robust fault interruption with dependable thermal and electromagnetic protection.
Featuring a K tripping characteristic and rated current of 15 A, the S804U-K15 is particularly suited to circuits supplying equipment with elevated starting or inrush currents. The K characteristic makes it suitable for motors, transformers and other inductive loads where normal starting currents could otherwise cause unwanted operation of the circuit breaker.
The S804U-K15 is designed for UL 489 branch circuit protection and has a specified short-circuit rating of 50 kA. Its four-pole configuration provides coordinated switching and protection across four conductors, while the S800 platform's current-limiting design helps reduce fault energy and electrical stress on downstream equipment.
