TJK636600 **Older Style** - 600Amp Circuit Breaker

TJK636600 **Older Style** - 600 Amp Circuit Breaker

The TJK636600 molded case circuit breaker is designed for dependable circuit protection in commercial and industrial electrical distribution systems that require a high-amperage, three-pole solution. Built with an older-style black-face configuration, this breaker is commonly used in existing installations where maintaining proper form, fit, and function is important for system compatibility. Its thermal magnetic trip unit protects against overloads and short circuits, while the internal common trip mechanism helps ensure all poles disconnect simultaneously during fault conditions.

As part of the GE Q-Line family, the TJK636600 features a bolt-on mounting design for secure installation and stable electrical connections in demanding environments. With a 600 amp rating and multiple interrupting capacities, it is well-suited for facilities operating large mechanical loads, HVAC equipment, distribution panels, and heavy-duty power systems. The included load-side lugs help simplify installation and conductor termination. Built to last and engineered for consistent operation, this breaker remains a practical replacement option for maintaining legacy electrical infrastructure.
