TJK436175 **Older Style** - 175Amp Circuit Breaker

TJK436175 **Older Style** - 175 Amp Circuit Breaker

The TJK436175 molded case circuit breaker is designed for your dependable circuit protection in commercial and industrial electrical distribution systems that require a 3-pole, 175 amp breaker with proven thermal magnetic trip protection. Built as part of the GE TJK4 Q-Line series, this bolt-on breaker features an older style black face configuration and is commonly used in existing panelboards and switchgear where matching form and fit are important for maintaining system compatibility. Its internal common trip mechanism helps provide coordinated interruption across all poles during overloads or short circuits, while the non-interchangeable thermal magnetic trip unit delivers consistent overcurrent protection for connected equipment and feeders. Designed to handle your demanding electrical environments, the TJK436175 includes load-side lugs for installation convenience and is HACR rated for use in heating, air conditioning, and refrigeration applications. Built to last and engineered for long-term serviceability, this breaker remains a practical replacement solution for maintaining legacy electrical systems without unnecessary modifications.
