Q4 Series, Plug In Circuit Breaker
Square D Q4 Series Plug-In circuit breakers are used in commercial and industrial electrical distribution panels designed to safeguard electrical circuits and equipment from damage caused by excessive currents or short circuits. When a fault occurs, they automatically trip and interrupt the current flow, preventing potential fire hazards and electrical accidents. They feature bolt-on connections for secure and reliable electrical connections. These circuit breakers have thermal and magnetic trip units, providing both long-time and instantaneous protection functions. They can interrupt a fault current of up to 25kA at 240V. These circuit breakers are available in 2 & 3-pole configurations.
