TJJ426200WL - 200Amp Circuit Breaker

TJJ426200WL - 200 Amp Circuit Breaker

The TJJ426200WL molded case circuit breaker is built for you to use in commercial and industrial electrical distribution systems that require dependable overcurrent protection. This 2-pole, 200-amp breaker is part of the Q-Line family and uses a thermal magnetic trip unit with internal common trip functionality to help you protect equipment from overloads and short circuits. Its cable-in/cable-out lug configuration allows for direct cable connections, and both line- and load-side lugs are included. That can help you to simplify installation in compatible switchboards and panel applications. The breaker is HACR rated, making it suitable for certain HVAC and refrigeration systems as well. With interrupting capacities rated at 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, the TJJ426200WL is commonly used in demanding electrical environments where matching existing equipment specifications is important. The non-interchangeable trip unit helps maintain consistent protection characteristics throughout the life of the breaker. Built with durability in mind, these breakers were made for long service life in the field.
