TJK626600WL **Older Style** 600Amp Circuit Breaker

TJK626600WL **Older Style** 600 Amp Circuit Breaker

The TJK626600WL is a 2-pole molded case circuit breaker used in your commercial and industrial electrical distribution systems. This model features the older style black face commonly found in existing Q-Line equipment, making it a good match for maintenance, repair, and replacement applications where equipment compatibility is important. Designed with a thermal magnetic trip unit, the breaker helps protect electrical systems from overloads and short circuits. The internal common trip mechanism allows both poles to trip together during a fault condition. This breaker also comes equipped with line and load-side lugs in a cable-in/cable-out configuration for direct cable connections. The TJK626600WL is often installed in panelboards, switchboards, and larger power distribution systems that require a 600 amp breaker with specific interrupting ratings. Its solid construction and familiar design make it well suited for long-term use in existing electrical systems.
