TJJ426175WL - 175Amp Circuit Breaker

TJJ426175WL - 175 Amp Circuit Breaker

The TJJ426175WL molded case circuit breaker is designed for dependable circuit protection in your commercial and industrial electrical distribution systems that require a 175-amp, 2-pole configuration. Built as part of the trusted Q-Line family, this thermal magnetic circuit breaker features an internal common trip mechanism and a non-interchangeable trip unit for consistent overcurrent and short-circuit protection. Its cable-in/cable-out lug-lug design simplifies installation in compatible switchboards and panel applications, while the included line- and load-side lugs help you secure conductor termination. With interrupting capacities rated up to 22k A.I.C. at 600VAC, 30k A.I.C. at 480VAC, and 42k A.I.C. at 240VAC, the TJJ426175WL is suited for demanding electrical systems where proper protection and equipment compatibility matter. HACR rating compatibility also makes it appropriate for heating, air conditioning, and refrigeration equipment applications. Built to last and engineered for reliable operation, this breaker is a practical solution for maintaining or replacing existing equipment in legacy power distribution systems.
