THQC2190WL - 90Amp Circuit Breaker

THQC2190WL - 90 Amp Circuit Breaker

The THQC2190WL circuit breaker is a 90-amp, 2-pole molded case circuit breaker designed to provide dependable overcurrent and short-circuit protection in your residential, commercial, and light industrial electrical distribution systems. As part of the trusted THQC Q-Line family, this breaker combines space-efficient performance with reliable circuit protection for applications requiring a higher amperage solution. Featuring an internal common trip mechanism, the THQC2190WL simultaneously disconnects both poles during a fault condition, helping you to protect connected equipment and wiring from damage while supporting electrical system safety.

Built with a cable-in/cable-out (lug-lug) configuration, the THQC2190WL offers convenient field installation and secure conductor termination. Its HACR rating makes it suitable for heating, air conditioning, and refrigeration equipment applications where dependable circuit protection is essential. With a 10kA interrupting capacity at 120/240VAC, this breaker is engineered to interrupt fault currents safely and maintain system integrity in demanding electrical environments.
