TJK436175WL - 175Amp Circuit Breaker

TJK436175WL - 175 Amp Circuit Breaker

The TJK436175WL molded case circuit breaker is designed for your dependable circuit protection in commercial and industrial electrical distribution systems requiring a 175 amp, 3-pole breaker with strong interrupting capabilities. Built as part of the trusted TJK4 Q-Line series, this breaker features a non-interchangeable thermal magnetic trip unit with internal common trip functionality to help you protect connected equipment and branch circuits from overloads and short circuits. Its cable-in/cable-out lug-lug configuration allows for straightforward installation in compatible panelboards and switchgear applications, while included line and load-side lugs help simplify setup in the field.

With interrupting ratings up to 42k AIC at 240VAC, 30k AIC at 480VAC, and 22k AIC at 600VAC, the TJK436175WL is well suited for facilities that require reliable overcurrent protection in higher fault-current environments. The breaker is also HACR rated, making it appropriate for heating, air conditioning, and refrigeration equipment applications where compatible equipment specifications call for HACR-rated protection. Built to last and engineered for long-term service in demanding environments, this molded case circuit breaker is commonly used in manufacturing facilities, commercial buildings, mechanical systems, and power distribution equipment where maintaining proper circuit protection is essential.
