THQD22150 - 150Amp Circuit Breaker

THQD22150 - 150 Amp Circuit Breaker

The THQD22150 is a 2-pole, 150-amp molded case circuit breaker designed for use in your compatible Q-Line distribution equipment and panelboard applications. Featuring a 22kA interrupting rating at 120/240VAC, this bolt-on circuit breaker helps provide dependable overcurrent and short-circuit protection in commercial, industrial, and institutional electrical systems. Its internal common trip mechanism ensures both poles trip simultaneously when an overcurrent condition occurs, helping you to protect connected equipment and branch circuits. Built for long-term service, the THQD22150 includes load-side lugs for convenient installation and secure conductor termination. The compact bolt-on design helps maintain a solid connection within approved panelboard assemblies. At the same time, its HACR rating makes it suitable for specific heating, air conditioning, and refrigeration applications, provided they are permitted by code and equipment requirements. When maintaining existing electrical infrastructure, this breaker provides the proper form, fit, and function required for compatible systems.
