THQD22125 - 125Amp Circuit Breaker

THQD22125 - 125 Amp Circuit Breaker

The THQD22125 is a 125-amp, 2-pole molded case circuit breaker designed for you to use in compatible Q-Line distribution equipment. It provides overcurrent and short-circuit protection in 120/240VAC electrical systems and features an internal common trip mechanism that opens both poles simultaneously when a fault occurs. This breaker uses a bolt-on mounting design and comes equipped with load-side lugs for field installation. With a 22kA interrupting rating, it is suitable for your applications where available fault current requires a higher interrupting capacity. The THQD22125 is also HACR rated, making it appropriate for heating, air conditioning, refrigeration, and other electrical distribution applications where that rating is specified. Built for long service life, this circuit breaker is commonly found in commercial facilities, industrial buildings, schools, healthcare facilities, and other environments that depend on reliable electrical protection.

Where It Works Best

• The THQD22125 is often used in commercial and industrial electrical systems that require a 125 amp, 2-pole breaker. Typical applications include panelboards, distribution equipment, HVAC systems, refrigeration equipment, and branch circuits where a bolt-on THQD breaker with a 22kA interrupting rating is required. It is frequently selected as a direct replacement when maintaining or servicing existing Q-Line installations.
