TJK636600 - 600Amp Circuit Breaker

TJK636600 - 600 Amp Circuit Breaker

The TJK636600 circuit breaker is a 600-amp, 3-pole, molded-case breaker designed for you to use in commercial and industrial electrical distribution systems. As part of the Q-Line series, this bolt-on breaker is commonly installed in panelboards and switchgear to provide dependable overcurrent protection for existing electrical systems. It uses a thermal magnetic trip unit with an internal common trip mechanism that disconnects all poles during an overload or short circuit condition. The breaker also includes load-side lugs, helping simplify installation and wiring connections in compatible equipment.

This breaker is HACR-rated, making it suitable for HVAC and refrigeration applications as well as general power distribution. Its molded case construction is built for long service life in demanding environments such as manufacturing facilities, commercial buildings, and utility systems. With interrupting ratings up to 22 kA at 600 VAC, the TJK636600 is intended for applications requiring reliable protection and compatibility with existing Q-Line systems.
