THQC32020WL - 20Amp Circuit Breaker

THQC32020WL - 20 Amp Circuit Breaker

The THQC32020WL is a 20-amp, 3-pole molded-case circuit breaker for your compatible Q-Line electrical distribution systems. Built with an internal common-trip mechanism, it trips all three poles simultaneously when an overload or short circuit occurs, making it a practical choice for protecting three-phase circuits and connected equipment.

This breaker features a cable-in/cable-out (lug-lug) configuration, allowing conductors to be terminated directly to the breaker. With a 10 kA interrupting rating at 240 VAC, it is suitable for a variety of commercial and industrial power distribution applications requiring dependable circuit protection. The HACR rating also makes it appropriate for qualifying heating, ventilation, air conditioning, and refrigeration systems.

Electrical systems often remain in service for decades, and replacement components need to match the original equipment. The THQC32020WL provides the form, fit, and function expected from the THQC series, helping you to maintain the integrity of compatible installations. Its molded case construction is built for long-term use in demanding environments where consistent circuit protection matters day after day.
