TJJ426225 - 225Amp Circuit Breaker

TJJ426225 - 225 Amp Circuit Breaker

The TJJ426225 is a 225 amp, 2-pole molded case circuit breaker designed for use in your commercial and industrial electrical distribution systems. As part of the Q-Line series, this breaker is commonly used in panelboards, switchboards, and HVAC-related applications where dependable circuit protection is required. Its bolt-on design allows for secure installation in compatible equipment, making it a practical replacement option for existing systems already using Type TJJ breakers.

Built with a thermal magnetic trip unit, the TJJ426225 responds to both overloads and short-circuit conditions to help you protect electrical equipment and conductors from damage. The breaker also features an internal common trip mechanism, which disconnects both poles during a fault condition. With interrupting ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, it is suited for a variety of demanding electrical environments.

This breaker includes load-side lugs for easier conductor termination and carries an HACR rating, making it suitable for heating, air conditioning, and refrigeration equipment applications. Its durable construction and compatibility with existing Q-Line systems make it a reliable choice for maintenance, repair, and replacement projects.
