Square D Q4 Series circuit breakers protect sensitive circuits from excessive current flows causing overloads or short circuits. These circuit breakers feature an over-centre toggle mechanism to provide quick make and break operation with positive handle indication. The thermal-magnetic trip elements are calibrated at an ambient temperature of 40 degrees Celsius to provide uniform tripping. They come with a push-to-trip button that enables the user to manually trip the circuit breaker and perform maintenance checks. Raptor Supplies offers a huge variety of these Q4 Series circuit breakers that can be mounted in any position.
