Why Choose the ABB S804U-Z80 High Performance MCB?
The ABB S804U-Z80 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 Z tripping characteristic and rated current of 80 A, the S804U-Z80 is intended for circuits requiring particularly sensitive short-circuit protection. The Z characteristic provides rapid magnetic operation at relatively low fault-current multiples, making it well suited to sensitive loads and circuits where fast fault disconnection is important.
The S804U-Z80 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 its current-limiting design helps reduce fault energy and electrical stress on downstream equipment.

Sensitive High-Performance Circuit Protection
The ABB S800U range provides branch circuit protection for demanding applications requiring compliance with UL 489. The S804U-Z80 combines thermal protection against sustained overloads with fast electromagnetic operation during short-circuit conditions while providing coordinated switching across four poles.
Its Z characteristic is intended for applications requiring a sensitive magnetic response, allowing the breaker to operate rapidly when fault current rises sufficiently above normal circuit conditions. Combined with its high short-circuit rating and current-limiting performance, this makes the S804U-Z80 suitable for protecting sensitive circuits in demanding electrical distribution systems.
Typical Applications
- Industrial electrical distribution equipment.
- Commercial power distribution systems.
- Machinery and automation control panels.
- Sensitive electrical and electronic circuits.
- UL 489 branch circuit protection applications.
- Circuits requiring rapid magnetic fault protection.
