TJK426225 - 225Amp Circuit Breaker

TJK426225 - 225 Amp Circuit Breaker

The TJK426225 molded case circuit breaker is designed for your dependable circuit protection in commercial and industrial electrical distribution systems where consistent operation and compatibility with existing equipment matter. Built as part of the GE Q-Line family, this 2-pole, 225-amp breaker features a thermal magnetic trip unit with internal common trip functionality to help you protect connected systems from overloads and short circuits. Its bolt-on mounting design supports secure installation in compatible panelboards and switchgear applications, while the included load-side lugs simplify conductor termination during maintenance or replacement projects. Designed for long-term service in demanding electrical environments, the TJK426225 is commonly used in facilities that require reliable power distribution protection at up to 600VAC.

Whether you are replacing an existing breaker in a legacy power system or maintaining a commercial electrical infrastructure, this breaker provides the form, fit, and function needed for compatible installations. The non-interchangeable trip unit configuration helps maintain the original system design characteristics, making it suitable for applications where specified trip settings must remain fixed. HACR rating further supports use in heating, air conditioning, and refrigeration equipment applications.
