Q2125HH - 125Amp Circuit Breaker

Q2125HH - 125Amp Circuit Breaker

The Q2125HH is a 125-amp, 2-pole Type HQP plug-in circuit breaker rated for 120/240VAC applications. One of its key advantages is its 65 kA A.I.C. rating, enabling it to interrupt fault currents up to 65,000 amps at its specified voltage. It's also HACR-rated so that it can be used in compatible heating, air-conditioning, and refrigeration applications. The plug-in design keeps things simple when working with equipment designed for Type HQP breakers, while its compact size 3.13 inches high, 2 inches wide, and 2.56 inches deep makes it easy to compare against an existing breaker. If you're replacing a Q2125HH, it's important to check the part number, but it's also worth checking the ratings. Confirm the 125A capacity, two-pole design, voltage, interrupting rating, dimensions, and breaker type before installation. That extra check can save a lot of trouble later.

Key Features and Benefits

• 125-amp rating for circuits designed around this amperage.
• Two-pole configuration for compatible 120/240VAC applications.

Where It Works Best

• The Q2125HH 125A circuit breaker makes sense for compatible electrical equipment that specifically calls for a Type HQP, 2-pole plug-in breaker. Its 120/240VAC rating and 65kA interrupting capacity can make it particularly useful in commercial, industrial, building electrical, and HVAC applications where those ratings are required.
