Overview

The ABB S804U-K80 High Performance Circuit Breaker (HPCB), SKU S804U-K80, is a 4-pole K-characteristic unit rated for 80 Amperes with a 50 kA interrupting capacity at 240/415 VAC. Designed for industrial power distribution, it provides precise overload and short-circuit protection for inductive loads, including motors and transformers. The K characteristic allows for higher inrush current tolerance, making it ideal for applications with frequent startup surges. This breaker is part of the ABB S804U series, compatible with the E4.2V-A 800 Ekip Hi-Touch LSI trip unit, offering advanced tripping curves and communication capabilities for system integration. With a frame rating of 800 Amperes and a withstand rating of 85 kA, it ensures reliable operation under fault conditions. Typical applications include HVAC systems, industrial machinery, and complex power panels where reliable circuit protection is critical. The S804U-K80 is manufactured in the US, ensuring compliance with North American electrical standards.
