TJK436200WL **Older Style** - 200Amp Circuit Breaker

TJK436200WL **Older Style** - 200 Amp Circuit Breaker

The TJK436200WL molded case circuit breaker is designed for your dependable circuit protection in commercial and industrial electrical distribution systems that require a 200-amp, 3-pole configuration. Built with an older-style black-face design, this breaker is commonly used as a form, fit, and functional replacement in existing installations where maintaining system compatibility is important. Its thermal magnetic trip unit protects against overloads and short circuits, while the internal common trip mechanism helps you to disconnect all poles simultaneously during fault conditions. The included line- and load-side lugs support cable-in/cable-out connections, making installation straightforward in a wide range of panel and switchgear applications. Designed for long-term service in demanding environments, the TJK436200WL is HACR-rated and suitable for HVAC, power distribution, and industrial control systems that require reliable protection.
