TJK426225WL **Older Style** - 225Amp Circuit Breaker

TJK426225WL **Older Style** - 225 Amp Circuit Breaker

When you're keeping an existing electrical system running smoothly, compatibility matters just as much as protection. The TJK426225WL molded case circuit breaker is designed for commercial and industrial applications that require a dependable form-fit-functional replacement for legacy equipment using the older style black face configuration. With a 225-amp rating and a 2-pole design, this breaker helps you to protect electrical systems against overloads and short circuits while fitting seamlessly into compatible distribution equipment already in service.

Built with a thermal magnetic trip unit and internal common trip functionality, the TJK426225WL responds to changing electrical conditions with consistent circuit protection for connected equipment and power distribution systems. The cable-in/cable-out lug-lug configuration allows for direct cable termination, making installation straightforward in many switchboard and panelboard setups. Included line- and load-side lugs help reduce installation prep time, which can be especially helpful during maintenance projects or scheduled shutdowns.

This breaker is commonly found in commercial facilities, manufacturing environments, HVAC systems, and industrial electrical infrastructure, where maintaining existing system design is important. Its durable construction reflects the kind of equipment built to handle years of daily operation in demanding environments.
