Cutler-Hammer QCL3025 U Three Phase Circuit Breaker

Cutler-Hammer QCL3025 U is a 25A, 240V three-phase circuit breaker (3P) that interrupts current on all three phases during overload or fault conditions. The unit is a 3-pole device identified by the model QCL3025 U, providing three-phase protection in 240V systems. With a 25 A rating at 240 V, this breaker is intended for installations that require overcurrent protection for three-phase circuits operating on a 240V supply. The three-pole design ensures simultaneous interruption of each phase, which helps protect conductors and connected equipment in multi-phase service. In practice, it is used to protect three-phase loads and circuits that operate from a 240-volt supply. The 3P configuration means tripping across all three phases at once, maintaining balanced protection in three-phase installations. Model QCL3025 U directly communicates its amperage, voltage, and 3P configuration for straightforward sourcing and replacement in compatible 3P 240V installations. This description focuses on the device's essential electrical characteristics and model identification to help buyers confirm compatibility when sourcing a replacement for 3P 240V service.
