THJK626600WL - 600Amp Circuit Breaker

THJK626600WL - 600 Amp Circuit Breaker

The THJK626600WL is a 2-pole, 600-amp molded case circuit breaker designed for use in your electrical distribution systems requiring dependable overcurrent and short-circuit protection. As part of the THJK6 Q-Line series, this circuit breaker features a thermal magnetic trip unit with an internal common trip and a non-interchangeable trip configuration, helping you to provide consistent circuit protection in commercial and industrial applications. Its cable-in/cable-out (lug-lug) design includes both line-side and load-side lugs for straightforward installation. Built to last and engineered for long-term service, the THJK626600WL is commonly used where high-amperage protection and reliable interruption capabilities are required. With interrupting ratings of 25kA at 600VAC, 35kA at 480VAC, and 65kA at 240VAC, this breaker is suitable for protecting electrical equipment and feeder circuits operating across a range of voltage systems. The HACR rating also makes it appropriate for heating, air conditioning, and refrigeration equipment applications where code-compliant overcurrent protection is required.
