ABB S281UC-Z25 is a 1-pole miniature circuit breaker (MCB) from ABB’s S200 UC family, featuring a Z-type trip curve and a rated current of 25 A. This single-pole device provides overcurrent protection by interrupting the circuit when current exceeds the preset value, helping prevent damage from overloads and short circuits in residential and light commercial electrical installations. Ideal for protecting branch circuits such as lighting, receptacle circuits, or small equipment circuits in ABB-compatible distribution panels.
