TJK426150WL - 150Amp Circuit Breaker

TJK426150WL - 150 Amp Circuit Breaker

The TJK426150WL molded case circuit breaker is built for you to use in commercial and industrial electrical distribution systems that require dependable overcurrent protection and compatibility with existing equipment. As part of the GE Q-Line series, this 2-pole, 150-amp breaker uses a thermal magnetic trip unit with an internal common trip to help you protect circuits from overloads and short circuits. The lug-lug configuration allows for cable-in/cable-out connections, making installation straightforward in many switchgear and panelboard setups. Line- and load-side lugs are included. With interrupting capacities rated at 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, this breaker is suitable for a wide range of power distribution applications. It is also HACR rated, making it compatible for use with heating, air conditioning, and refrigeration equipment where applicable. Built with durability in mind, the TJK426150WL is often used in systems where maintaining the correct fit and electrical specifications is important.
