TJK436225WL **Older Style** - 225Amp Circuit Breaker

TJK436225WL **Older Style** - 225 Amp Circuit Breaker

The TJK436225WL molded case circuit breaker is designed for your dependable protection in commercial and industrial electrical distribution systems, where maintaining compatibility with existing equipment is critical. Built with an older-style black-face configuration, this 225-amp, 3-pole breaker features a thermal-magnetic trip unit with an internal common trip, helping you protect connected systems from overloads and short circuits while supporting consistent operation in legacy installations. Its cable-in/cable-out lug-lug design includes both line- and load-side lugs for secure conductor termination and easier integration into compatible panelboards and switchgear. As part of the Q-Line series, the TJK436225WL is commonly used in facilities that require reliable branch or feeder circuit protection and have established equipment layouts. Built to last and engineered for long-term serviceability, this breaker is a practical form, fit, and functional replacement for compatible systems operating at up to 600VAC.
