TJJ436200 - 200Amp Circuit Breaker

TJJ436200 - 200 Amp Circuit Breaker

When you’re working with existing commercial or industrial electrical equipment, finding the right breaker is about more than just matching amperage. The TJJ436200 molded case circuit breaker is built for applications where proper fit, dependable protection, and compatibility with existing systems all matter. Designed as part of the Q-Line family, this 3-pole, 200-amp breaker is commonly used in power distribution systems that require reliable overcurrent protection for three-phase applications up to 600VAC.

This breaker uses a thermal magnetic trip unit that reacts to both sustained overloads and sudden short circuits, helping protect connected equipment from electrical damage and unnecessary downtime. The internal common trip mechanism ensures all poles disconnect together during a fault condition, which is especially important in three-phase systems where balanced protection is critical. Its bolt-on mounting style provides a secure installation in compatible panelboards and switchgear, while the included load-side lugs help make field installation more straightforward.

The TJJ436200 is also HACR rated, making it a suitable choice for HVAC equipment, refrigeration systems, motor loads, and other demanding commercial applications. With interrupting ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, this breaker is designed to handle fault conditions in a wide range of operating environments. Built to last and intended for long-term service, it remains a practical solution for maintaining and servicing existing electrical infrastructure where matching specifications and dependable operation are essential.
