Why Choose the ABB S801U-Z30 High Performance MCB?
The ABB S801U-Z30 is a compact and highly reliable 1-pole high performance miniature circuit breaker (MCB) designed to protect electrical circuits against overload and short-circuit conditions. As part of the ABB S800U high performance circuit breaker series, it combines a 30 A rated current, Z tripping characteristic and high short-circuit interruption capability for demanding industrial and commercial electrical systems.
The S801U-Z30 uses thermal and electromagnetic tripping mechanisms to provide dependable overcurrent protection. Its Z characteristic provides sensitive short-circuit response, making it particularly suitable for circuits containing sensitive electronic equipment, control devices and other loads where comparatively low fault currents require rapid disconnection.
With a short-circuit breaking capacity of up to 30 kA and a single-pole configuration, the S801U-Z30 is designed for high-performance branch-circuit protection. Its UL 489 certification and compact DIN-rail format make it suitable for industrial control panels, machinery, automation equipment and electrical distribution systems.

Sensitive and Reliable Circuit Protection
High-performance miniature circuit breakers such as the ABB S801U-Z30 automatically disconnect a circuit when excessive current occurs. The thermal tripping mechanism responds to sustained overload conditions, while the electromagnetic mechanism provides rapid interruption during short circuits, helping protect conductors and connected electrical equipment.
The Z characteristic is intended for applications requiring a comparatively sensitive magnetic response. This makes the S801U-Z30 particularly useful for electronic equipment, control circuits and other installations where available fault currents may be lower than those encountered in circuits protected by breakers with less sensitive instantaneous characteristics.
Typical Applications
- Industrial control panels and switchgear.
- Electronic equipment and sensitive electrical loads.
- Automation and process control circuits.
- Industrial machinery and production equipment.
- Branch-circuit protection in UL-based installations.
- Commercial and industrial electrical distribution systems.
