Description
Designed for demanding industrial control applications, the S280UC series provides versatile UL 1077 supplementary protection. This 1A, single-pole breaker safely handles both AC and DC voltages with a specialized K-curve trip. It mounts securely onto standard DIN rail enclosures. As a legacy component, it serves as an exact replacement for older systems, while new builds use the S201MUC-K1. To safely interrupt DC faults, it incorporates a permanent magnet for rapid arc extinguishing.
