Why Choose the ABB S201M-Z3UC Miniature Circuit Breaker?
The ABB S201M-Z3UC, order code 2CDS271061R0318, 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 reliable overload and short-circuit protection for sensitive industrial, control and direct-current circuits.
Rated at 3 A with a Type Z tripping characteristic, the S201M-Z3UC provides sensitive magnetic protection for circuits where rapid disconnection at relatively low multiples of rated current is required. Its universal-current construction enables operation in both AC and DC systems, including applications at 230 V AC and up to 220 V DC in a single-pole configuration.
The S201M-Z3UC 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 and compatibility with ABB System pro M compact® accessories make it a flexible protection solution for automation, instrumentation, machinery and industrial DC systems.

Sensitive Universal-Current Circuit Protection
The ABB S201M-Z3UC combines thermal overload protection with a sensitive magnetic short-circuit release. Its Type Z characteristic makes it particularly suitable for sensitive electrical and electronic circuits where rapid interruption at comparatively low fault-current multiples is required, while its 3 A rating supports low-current industrial control and auxiliary applications.
The S 200 M UC range is engineered specifically for universal-current operation and can protect both AC and DC circuits. The single-pole S201M-Z3UC supports DC applications up to 220 V DC, while multi-pole configurations within the wider range can support higher DC system voltages. Correct polarity must be observed when installing the device in DC applications.
Typical Applications
- Industrial low-current control circuits.
- Sensitive electronic and instrumentation circuits.
- AC and DC electrical distribution panels.
- Automation and machine control systems.
- Long cable circuits in appropriate TN and IT systems.
- DC auxiliary and battery-powered systems.
- Railway and transportation electrical equipment.
- OEM machinery and industrial control-panel construction.
