ABB S281UC-Z6 Circuit Breaker

ABB S281UC-Z6 is a 1‑pole miniature circuit breaker from ABB’s S200 UC family, delivering Z‑curve overcurrent protection for a single branch circuit. Rated for 6 A, it is designed for DIN‑rail mounting in low‑voltage distribution panels and is UL 1077 listed within the UC lineup. The UC variants include a permanent‑magnet arc‑extinguishing feature that aids rapid interruption of faults and provides current‑limiting protection characteristic typical of ABB’s S200 UC devices. This model is commonly used to protect small loads in control panels, lighting circuits, and other low‑current applications where precise, time‑dependent tripping is required. As the 1P, 6 A version in ABB’s S200 Miniature Circuit Breaker family, the S281UC-Z6 combines compact form factor with reliable overcurrent protection suitable for modular panel designs and retrofit projects where ABB equipment is preferred.
