TJJ426200 - 200Amp Circuit Breaker

TJJ426200 - 200 Amp Circuit Breaker

The TJJ426200 molded case circuit breaker is a solid choice for protecting your electrical distribution systems in commercial and industrial settings. Designed as part of the Q-Line family, this 2-pole, 200-amp breaker uses a thermal magnetic trip unit to respond to overloads and short circuits before damage can spread through the system. Its bolt-on design helps you to provide a secure connection inside compatible panelboards and switchgear, making it a practical replacement option for existing equipment layouts. The internal common trip mechanism allows both poles to trip together when needed, helping maintain safer operation across connected circuits. With included load-side lugs and HACR rating support, the TJJ426200 is often used in HVAC systems, manufacturing facilities, and general power distribution applications where dependable protection and proper equipment compatibility are important.
