TJK636600WL - 600Amp Circuit Breaker

TJK636600WL - 600 Amp Circuit Breaker

The TJK636600WL molded case circuit breaker is designed for your dependable circuit protection in commercial and industrial electrical distribution systems requiring a 600 amp, 3-pole configuration. Built as part of the GE / ABB Q-Line series, this breaker features a non-interchangeable thermal magnetic trip unit with internal common trip functionality to help you protect connected equipment from overloads and short circuits. Its cable-in/cable-out lug-lug design simplifies installation in compatible panelboards and switchgear applications, while the included line- and load-side lugs support secure conductor termination. Engineered for long service life in demanding environments, the TJK636600WL is commonly used in facilities where consistent power distribution and reliable branch protection are essential.

With interrupting capacities rated at 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, this breaker is suitable for a wide range of heavy-duty electrical systems. The HACR rating also makes it appropriate for heating, air conditioning, and refrigeration applications where approved overcurrent protection is required. Its compact molded case construction helps conserve panel space while maintaining the form, fit, and function needed for existing compatible systems and replacement projects.
