TJK426200 **Older Style** - 200Amp Circuit Breaker

TJK426200 **Older Style** - 200 Amp Circuit Breaker

The TJK426200 is a 2-pole, 200-amp molded-case circuit breaker designed for you to use in commercial and industrial electrical distribution systems requiring dependable overcurrent protection in legacy equipment configurations. Built as part of the Q-Line family, this Type TJK4 breaker features a thermal magnetic trip unit with internal common trip functionality, helping you protect connected circuits from overloads and short circuits while maintaining coordinated operation between poles. Its bolt-on mounting design supports secure installation in compatible panelboards and switchgear applications, making it a practical form, fit, and functional replacement for existing systems.

This older-style black-face Configuration is commonly used in facilities where maintaining compatibility with existing electrical infrastructure is important. The breaker includes load-side lugs for straightforward conductor termination and is HACR-rated, making it suitable for heating, air conditioning, and refrigeration applications when properly specified. Designed for long-term service in demanding environments, the TJK426200 combines durable construction with field-proven thermal-magnetic protection technology trusted across industrial plants, commercial buildings, manufacturing facilities, and utility installations.
