Why Choose the ABB S201M-Z8UC Miniature Circuit Breaker?
The ABB S201M-Z8UC, order code 2CDS271061R0408, is a high-performance single-pole miniature circuit breaker (MCB) for AC and DC applications. Part of the ABB System pro M compact® S 200 M UC series, it provides dependable overload and short-circuit protection for sensitive industrial, control and direct-current circuits.
Rated at 8 A with a Type Z tripping characteristic, the S201M-Z8UC provides sensitive magnetic fault protection for circuits where rapid disconnection at relatively low multiples of rated current is required. Its universal-current design supports both AC and DC applications, including operation at 230 V AC and up to 220 V DC in a single-pole configuration.
The S201M-Z8UC provides an ultimate short-circuit breaking capacity of 10 kA at 230 V AC and 10 kA at 220 V DC, increasing to 20 kA at 110 V DC. Compact DIN-rail construction, a 17.5 mm module width and compatibility with ABB System pro M compact® accessories make it a versatile protection solution for automation, instrumentation, machinery and transportation systems.

Sensitive Type Z Universal-Current Protection
The ABB S201M-Z8UC combines thermal overload protection with a sensitive magnetic short-circuit release. Its Type Z characteristic is intended for applications where rapid interruption at comparatively low multiples of rated current is required, making it suitable for appropriately selected sensitive electronic, instrumentation and control circuits.
The S 200 M UC family is designed for universal-current applications and supports both AC and DC installations. The single-pole S201M-Z8UC can be applied at up to 220 V DC, while retaining a compact one-module footprint for efficient integration into industrial distribution boards and control panels. Correct polarity and ABB's specified connection arrangement must be observed in DC applications.
Typical Applications
- Industrial low-current control circuits.
- Sensitive electronic and instrumentation circuits.
- Automation and machine control systems.
- AC and DC industrial distribution panels.
- DC auxiliary and battery-supplied circuits.
- Railway and transportation electrical systems.
- Appropriate sensitive-load and long-cable circuits.
- OEM machinery and industrial control-panel construction.
