TJ226225 - 225A Circuit Breaker

TJ226225 - 225A Circuit Breaker

The TJ226225 circuit breaker is a 225-amp, 2-pole thermal-magnetic breaker designed for you to use in commercial and industrial electrical distribution systems. Built on the TJ frame platform, this breaker provides overload and short-circuit protection for equipment operating on up to 480VAC systems. Its non-interchangeable trip unit helps you to maintain consistent protection settings, while the included load-side terminals make installation more straightforward during maintenance or replacement work. Rated for 40°C applications, the TJ226225 is often used in existing switchboards, panelboards, and distribution equipment where matching frame size and electrical specifications are important. The breaker’s compact design also makes it a practical choice for facilities working within limited equipment space. Built to last, this model is intended for form, fit, and functional replacement in compatible systems.
