TJK436200 - 200Amp Circuit Breaker

TJK436200 - 200 Amp Circuit Breaker

The TJK436200 molded case circuit breaker is built for you to use in commercial and industrial electrical distribution systems that require dependable 3-phase circuit protection. This 3-pole, 200 amp breaker uses a thermal magnetic trip unit to respond to overloads and short circuits, helping you protect connected equipment and wiring from damage during fault conditions. Its internal common trip design allows all poles to disconnect together when needed, supporting safe operation across the system.

Designed as part of the Q-Line series, the TJK436200 features a bolt-on mounting style for installation in compatible panelboards and distribution equipment. The breaker also includes load-side lugs, helping streamline installation and replacement work in existing setups. With interrupting ratings up to 22k at 600VAC, it is suited for a range of commercial power distribution applications, including HVAC equipment, motor loads, and facility electrical systems. Its molded case construction is made for long-term service in demanding environments where reliable protection matters.
