Why Choose the ABB S801U-Z40 High Performance MCB?
The ABB S801U-Z40 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 40 A rated current, Z tripping characteristic and high short-circuit interruption capability for demanding industrial and commercial electrical systems.
The S801U-Z40 uses thermal and electromagnetic tripping mechanisms to provide dependable overcurrent protection. Its Z characteristic provides a sensitive magnetic response, making it particularly suitable for circuits containing electronic equipment, control devices and other loads where rapid disconnection at comparatively low short-circuit currents is required.
With a short-circuit breaking capacity of up to 30 kA and a single-pole configuration, the S801U-Z40 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-Z40 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, connected equipment and electrical installations.
The Z characteristic is intended for applications requiring a comparatively sensitive magnetic response. This makes the S801U-Z40 particularly useful for electronic equipment, control circuits and other installations where rapid fault disconnection is important, while its high interruption capability supports use in systems with significant prospective short-circuit currents.
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.
