Why Choose the ABB S401M-UCC1 DC Miniature Circuit Breaker?
The ABB S401M-UCC1 is a compact single-pole miniature circuit breaker (MCB) designed for DC circuit protection within the ABB SMISSLINE TP plug-in distribution system. It provides overload and short-circuit protection for direct-current applications while retaining the installation advantages of ABB's touch-proof plug-in architecture.
As part of the ABB S400 M-UC series, the S401M-UCC1 is specifically engineered for DC applications and uses a C tripping characteristic according to IEC/EN 60947-2. The single-pole version is designed for applications up to 220 V DC, making it suitable for control power, automation, signalling and other low-voltage DC distribution circuits.
The S401M-UCC1 has a 1 A rated current, occupies one 18 mm module and weighs approximately 145 g. ABB identifies this exact variant under order code 2CCS561001R1014 and EAN / GTIN 7612270109753.

Reliable DC Circuit Protection for SMISSLINE TP Systems
Direct-current circuits require protective devices designed to interrupt DC fault currents reliably because, unlike alternating current, DC does not naturally pass through a zero-current point every cycle. The ABB S400 M-UC range is specifically designed for DC applications, providing overload and short-circuit protection in compatible low-voltage distribution systems.
The S401M-UCC1 combines this DC capability with the modular ABB SMISSLINE TP architecture. Its 1 A C-curve rating makes it particularly suitable for lower-current auxiliary, control and signalling circuits, while the plug-in format supports efficient installation and replacement within compatible SMISSLINE assemblies.
Typical Applications
- ABB SMISSLINE TP DC distribution systems.
- Industrial DC control circuits.
- Automation and PLC auxiliary supplies.
- DC signalling and monitoring circuits.
- Control-panel power distribution.
- Building automation systems.
- Commercial and industrial low-voltage DC installations.
