TJK636500WL **Older Style** - 500A Circuit Breaker

TJK636500WL **Older Style** - 500A Circuit Breaker

The TJK636500WL Older Style Black Face molded case circuit breaker is designed for your dependable protection in commercial and industrial electrical distribution systems that require a reliable 500 amp, 3-pole breaker configuration. Built as part of the trusted Q-Line family, this breaker features a thermal magnetic trip unit with internal common trip functionality to help protect connected equipment from overloads and short circuits. Its cable-in/cable-out lug-lug design includes both line-side and load-side lugs for straightforward installation in compatible legacy systems and switchgear applications.

With interrupting ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, the TJK636500WL is suited for demanding power distribution environments where maintaining proper circuit protection is critical. The older style black face configuration makes it a practical form, fit, and function replacement for existing installations using compatible TJK6 series equipment. Built with long-term service applications in mind, this breaker is commonly used in manufacturing facilities, commercial buildings, utility distribution setups, and heavy-duty electrical panels where consistent operation matters every day.
