TJK436200 **Older Style** - 200Amp Circuit Breaker

TJK436200 **Older Style** - 200 Amp Circuit Breaker

The TJK436200 molded case circuit breaker is designed for your dependable protection in commercial and industrial electrical distribution systems where maintaining compatibility with existing equipment matters. Built as part of the Q-Line Type TJK4 series, this 3-pole breaker features a 200 amp thermal magnetic trip unit with internal common trip functionality to help you protect connected systems from overloads and short circuits. Its older style black face design makes it a practical form, fit, and functional replacement for matching legacy installations and existing panel configurations.

Engineered for use in demanding electrical environments, the TJK436200 includes load-side lugs for installation convenience and carries an HACR rating, making it suitable for heating, air conditioning, and refrigeration applications. With interrupting ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC, this breaker is built to last while supporting safe operation across a range of commercial power distribution systems. The bolt-on mounting configuration helps provide a secure connection in compatible panelboards and switchgear assemblies where reliability and proper fit are essential.
