THQC2150WL - 50Amp Circuit Breaker

THQC2150WL - 50 Amp Circuit Breaker

The THQC2150WL circuit breaker is a dependable 50-amp, 2-pole molded case circuit breaker designed to provide reliable overcurrent and short-circuit protection in your residential, commercial, and light industrial electrical systems. As part of the trusted THQC Q-Line series, this breaker features an internal common trip mechanism that simultaneously disconnects both poles when a fault condition occurs, helping you to protect connected equipment and electrical circuits from damage. Its cable-in/cable-out (lug-lug) configuration offers installation flexibility, while the compact design makes it a practical solution for panelboard and distribution applications where space efficiency matters.

Built for performance in 120/240VAC systems, the THQC2150WL delivers a 10kA interrupting capacity (AIC), helping safeguard electrical infrastructure against potentially damaging fault currents. The breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration equipment applications. Whether used for branch circuit protection, HVAC systems, subpanels, or general power distribution, this breaker offers the durability and dependable operation that electrical professionals expect from a molded case circuit breaker.
