TJK626450WL **Older Style** - 450Amp Circuit Breaker

TJK626450WL **Older Style** - 450 Amp Circuit Breaker

The TJK626450WL is a 2-pole, 450-amp molded case circuit breaker designed for you to use in commercial and industrial electrical distribution systems. Built in the Q-Line TJK6 frame style, this breaker features the older style black face commonly found in existing legacy equipment. It uses a thermal magnetic trip unit with internal common trip protection to help interrupt overloads and short circuits when fault conditions occur. The cable-in/cable-out lug-lug configuration allows for straightforward installation in compatible switchboards and panel systems, and both line- and load-side lugs are included. This breaker is often used as a direct replacement in applications where matching form, fit, and electrical ratings matters.
