TJJ436150 - 150Amp Circuit Breaker

TJJ436150 - 150 Amp Circuit Breaker

When you’re maintaining an existing electrical distribution system, compatibility and dependable protection matter; the TJJ436150 molded case circuit breaker is built for exactly that purpose. Designed as part of the well-known Q-Line family, this 3-pole, 150-amp circuit breaker delivers the form, fit, and function needed for a wide range of commercial and industrial applications. Whether it’s installed during a facility upgrade, a service replacement, or ongoing maintenance work, this breaker is designed to integrate with compatible systems without unnecessary complications.

The TJJ436150 uses a thermal magnetic trip unit with an internal common trip, helping protect equipment and conductors from overloads and short circuits while ensuring all poles disconnect together during a fault condition. Its bolt-on mounting design provides a secure connection within compatible panelboards and switchgear, while the included load-side lugs simplify field installation. Because it carries HACR certification, this breaker is also suitable for heating, air conditioning, and refrigeration equipment applications where reliable circuit protection is essential.

Built to handle demanding electrical environments, the TJJ436150 offers interrupting capacities of 22 kA at 600 VAC, 30 kA at 480 VAC, and 42 kA at 240 VAC. That combination of ratings makes it a practical choice for facilities operating across different voltage systems. From manufacturing plants and commercial buildings to HVAC distribution systems, this breaker continues to be used in applications where long-lasting electrical protection and equipment compatibility are important.
