Why Choose the ABB S402M-UCC1 DC Miniature Circuit Breaker?
The ABB S402M-UCC1 is a high-performance two-pole miniature circuit breaker (MCB) designed for reliable protection of AC and DC circuits within the ABB SMISSLINE TP plug-in distribution system. With a 1 A rated current and UC-C / Type C tripping characteristic, it protects conductors and connected equipment against overload and short-circuit conditions.
As part of the ABB S400M-UC series, the S402M-UCC1 combines dependable thermal-magnetic circuit protection with the flexibility of ABB's SMISSLINE TP architecture. Its two-pole configuration enables simultaneous protection and disconnection of two conductors, while the plug-in design supports efficient installation, maintenance and modification of compatible distribution assemblies.
The S402M-UCC1 is suitable for operation up to 440 V DC in a two-pole configuration and is also suitable for AC applications. Its low 1 A rated current makes it particularly useful for control, signalling, instrumentation and other low-current circuits where reliable overcurrent protection is required.
