Square D HDA261504AABCSJYP 261504A 2-Pole 600 V Circuit Breaker

Shield your electrical system with the Square D HDA261504AABCSJYP, a dependable 2-pole, 600 V circuit breaker engineered for demanding commercial and light-industrial panels. This specific HDA261504AABCSJYP part delivers reliable overcurrent protection and precise disengagement when faults occur, helping safeguard wiring, equipment, and personnel.

Why this 2-pole, 600 V design matters

Two-pole breakers disconnect both hot conductors simultaneously, ensuring a complete shutoff for multi-wire branch circuits. The 600 V rating expands protection into higher-voltage distribution environments, minimizing nuisance trips and providing compatibility with common industrial equipment and panel types that use Square D protection devices.
