TJK426225 **Older Style** - 225 Amp Circuit Breaker

The TJK426225 Older Style Black Face molded case circuit breaker is a dependable choice for maintaining and protecting your commercial and industrial electrical systems that still rely on proven legacy equipment. Built as part of the well-known Q-Line series, this 2-pole, 225-amp breaker is designed to provide consistent circuit protection in applications where proper fit, electrical compatibility, and reliable operation are essential. Its older style black face design makes it particularly useful for matching existing installations without changing the look or layout of the equipment already in service.

Inside, the breaker uses a non-interchangeable thermal magnetic trip unit with internal common trip functionality to help you protect connected systems from overloads and short circuits. The bolt-on mounting configuration provides a secure connection in compatible panelboards and switchgear, while the included load-side lugs help simplify installation and maintenance work in the field. With interrupting ratings up to 22k A.I.C. at 600VAC, the TJK426225 is well-suited for handling demanding electrical loads commonly found in HVAC equipment, motor applications, distribution panels, and industrial power systems.

For facilities looking to keep existing electrical infrastructure operating safely and efficiently, this breaker delivers the form, fit, and function needed for many established systems. Built to last and designed for long-term service, the TJK426225 remains a practical solution for commercial and industrial environments where dependable circuit protection matters every day.
