TJJ426200 **Older Style** - 200Amp Circuit Breaker

TJJ426200 **Older Style** - 200 Amp Circuit Breaker

The TJJ426200 molded case circuit breaker is designed for use in commercial and industrial electrical systems that require dependable overcurrent protection in a compact, bolt-on design. This 2-pole, 200-amp breaker features the older style black face configuration commonly found in existing Q-Line installations, making it a practical choice when matching installed equipment and panel layouts is important.

Built with a thermal magnetic trip unit and internal common trip mechanism, the TJJ426200 helps you to protect connected equipment from overloads and short circuits while maintaining consistent operation in day-to-day service environments. The non-interchangeable trip setup keeps the breaker configured to its original factory specifications, and included load-side lugs help streamline installation. Its HACR rating also makes it suitable for HVAC and refrigeration applications where reliable circuit protection is required.

Constructed for long-term use in demanding electrical systems, this breaker is often used in panelboards, distribution equipment, and facility maintenance projects where compatibility and proper fit matter just as much as electrical ratings.
