THQC32050WL - 50Amp Circuit Breaker

THQC32050WL - 50 Amp Circuit Breaker

The THQC32050WL is a 50-amp, 3-pole molded case circuit breaker built for protecting your three-phase electrical circuits from overloads and short circuits. Part of the THQC Q-Line family, this breaker features an internal common trip mechanism, which means all three poles trip together when a fault occurs. That added level of protection is especially important for three-phase equipment and motor-driven systems. With a 10kA interrupting rating at 240VAC, the THQC32050WL is suitable for many commercial and industrial electrical applications where dependable circuit protection is required. Its cable-in/cable-out (lug-lug) design allows conductors to be landed directly on the breaker, making it a practical option for panel installations, equipment feeds, and distribution systems. The breaker is also HACR rated, making it appropriate for use with heating, air conditioning, and refrigeration equipment. Whether you're replacing an existing breaker or installing new electrical distribution equipment, the THQC32050WL provides the protection needed to help keep systems operating safely and efficiently.
