THQB2140GF - 40Amp Circuit Breaker

THQB2140GF - 40 Amp Circuit Breaker

The THQB2140GF is a 40-amp, 2-pole bolt-on circuit breaker designed for you to use in compatible Q-Line panelboards operating on 120/240VAC systems. With a 10kA interrupting rating, this molded-case breaker helps you to protect electrical circuits from overcurrent damage while providing ground-fault protection where required. Its bolt-on construction allows for a secure connection within the panel, making it a practical choice for maintaining existing electrical distribution equipment.

This breaker is commonly found in commercial and industrial installations, including applications involving HVAC and refrigeration equipment. Because it is HACR rated, it can be used on approved heating, air conditioning, and refrigeration circuits. The THQB2140GF is built for long service life and is intended to match the form, fit, and function requirements of compatible systems already in operation.
