Cutler-Hammer CHH3125 Molded Case Circuit Breaker

The Cutler-Hammer CHH3125 molded case circuit breaker is a 125A, 240V, three-pole device designed to provide overcurrent protection for three-phase electrical circuits. As part of the CHH family, the CHH3125 is configured for 3P operation, delivering simultaneous disconnection of all three conductors in a 240V system. The 125A rating indicates the maximum continuous current the unit is intended to carry under normal operation, with trip action triggered when service conditions exceed that limit. This model supports typical commercial and light industrial distribution setups where reliable protection of feeders and branch circuits is required in 240V three-phase networks. The molded case construction aids durability in standard electrical panels and enclosures, helping maintain safe, organized enclosure interiors while providing a compact protective solution for three-phase equipment. Designed for use in applications that rely on 240V three-phase power, the CHH3125 offers a straightforward, non-intuitive hardware interface for panel mounting and circuit protection within compatible Eaton/Cutler-Hammer installations.
