TJK636500WL - 500Amp Circuit Breaker

TJK636500WL - 500 Amp Circuit Breaker

The TJK636500WL molded case circuit breaker is built for your commercial and industrial electrical systems that require dependable 500 amp circuit protection. Designed as part of the TJK6 Q-Line series, this 3-pole breaker uses a thermal magnetic trip unit to help protect equipment and electrical distribution systems from overloads and short circuits. Its cable-in/cable-out lug configuration includes both line and load lugs, helping simplify installation in compatible setups. The internal common trip mechanism allows all poles to trip together when needed, supporting safe operation across three-phase applications. With HACR certification and multiple interrupting ratings for common voltage systems, the TJK636500WL is often used in panelboards, switchgear, and equipment distribution applications where reliable protection and proper system compatibility are important.
