TJK426150 - 150Amp Circuit Breaker

TJK426150 - 150 Amp Circuit Breaker

When your dependable circuit protection matters, the TJK426150 molded case circuit breaker delivers the form, fit, and function needed for many commercial and industrial electrical systems. Designed for the Q-Line series, this 2-pole, 150-amp breaker provides consistent overcurrent protection without unnecessary complexity. Its thermal magnetic trip unit responds to both overloads and short circuits, helping you to protect connected equipment while supporting smooth day-to-day operation in demanding environments.

The bolt-on design provides a secure fit in compatible electrical distribution equipment, making the TJK426150 a practical solution for panelboards, switchgear, and HVAC systems. Because it includes an internal common trip mechanism, both poles trip together when needed, adding another layer of coordinated protection for connected circuits. The included load-side lugs also help simplify installation and maintenance tasks for electricians and facility teams.

With interrupting ratings of 22k A.I.C. at 600VAC, 30k A.I.C. at 480VAC, and 42k A.I.C. at 240VAC, this molded-case circuit breaker is well-suited for a wide range of voltage applications in commercial buildings, manufacturing facilities, and industrial operations. Its HACR rating makes it a reliable fit for heating, air conditioning, and refrigeration equipment that require dependable circuit protection. Built to last and designed for compatibility with existing systems, the TJK426150 remains a trusted choice for safely and efficiently maintaining electrical infrastructure.
