THQC32020WL - 20Amp Circuit Breaker

THQC32020WL - 20 Amp Circuit Breaker

The THQC32020WL is a 20-amp, 3-pole molded case circuit breaker designed for protecting your three-phase electrical circuits from overloads and short circuits. Featuring an internal common trip mechanism, all three poles open simultaneously when a fault is detected, helping you maintain safe operation of connected equipment and electrical systems. This breaker belongs to the THQC Q-Line series and utilizes a cable-in/cable-out (lug-lug) connection design for straightforward installation in compatible distribution equipment. With a 10kA interrupting rating at 240VAC, it is built to handle fault conditions commonly encountered in commercial and industrial power systems. The breaker is also HACR rated, making it suitable for heating, air conditioning, and refrigeration applications. Its compact molded case construction helps you to conserve valuable panel space while providing reliable circuit protection. Whether installed in a panelboard, HVAC system, machinery circuit, or other three-phase application, the THQC32020WL delivers dependable performance where consistent electrical protection is required.
