THQC2140WL - 40Amp Circuit Breaker

THQC2140WL - 40 Amp Circuit Breaker

The THQC2140WL is a 40-amp, 2-pole molded case circuit breaker built for protecting your 120/240VAC electrical circuits from overloads and short circuits. Part of the Q-Line family, this breaker features an internal common trip mechanism that disconnects both poles simultaneously when a fault occurs. That added level of protection is especially important for equipment and circuits that require both conductors to be shut off together.

With its lug-lug, cable-in/cable-out design, the THQC2140WL is well suited for applications where straightforward field wiring is needed. The breaker carries a 10kA interrupting rating at 120/240VAC and is HACR rated for use with heating, air conditioning, and refrigeration equipment. Its compact size makes it a practical choice for your panel installations where space matters without sacrificing circuit protection.

Where It Works Best

• The THQC2140WL is commonly used in residential and commercial electrical systems, particularly where 240-volt loads are present. It is a good fit for HVAC equipment, air conditioning units, refrigeration systems, subpanels, and other branch circuits requiring a 40-amp, 2-pole breaker. The common-trip design helps ensure both poles disconnect together when protection is needed, helping safeguard connected equipment and wiring.
