TQDL21175 - 175Amp Circuit Breaker

TQDL21175 - 175 Amp Circuit Breaker

The TQDL21175 circuit breaker is designed for you to protect electrical systems that require dependable 175-amp overcurrent protection in a compact, plug-on design. This 2-pole thermal magnetic breaker features an internal common trip mechanism that helps disconnect both poles simultaneously during overloads or short circuits. With a 10k A.I.C. rating at 120/240 VAC and HACR certification, it is frequently used in commercial buildings, industrial equipment, and HVAC applications where maintaining the original panel configuration is important. Its design requires four 1-inch panel spaces, making it a practical fit for your compatible load centers and panelboards that are already built around TQDL-style breakers. Built for long service life, the TQDL21175 helps keep electrical distribution systems operating safely and efficiently without unnecessary complexity.
