TJK626600 - 600Amp Circuit Breaker

TJK626600 - 600 Amp Circuit Breaker

The TJK626600 molded case circuit breaker is designed for your commercial and industrial electrical distribution systems that require dependable overcurrent protection in higher-amperage applications. Built as part of the GE / ABB Q-Line family, this 2-pole breaker features a non-interchangeable thermal magnetic trip unit with internal common trip functionality to help you protect connected equipment and circuits from overloads and short circuits. Its bolt-on mounting configuration supports secure installation in compatible panelboards and switchgear, while the included load-side lugs help simplify field connections. With interrupting ratings up to 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, the TJK626600 is well suited for demanding power distribution environments where consistent protection and compatibility with existing systems are important. HACR rating capability also makes it appropriate for certain heating, air conditioning, and refrigeration applications. Built to last, this breaker is commonly used in facilities that depend on durable electrical infrastructure and long-term serviceability.
