Q2125H - 125Amp Circuit Breaker

Q2125H - 125Amp Circuit Breaker

When you're replacing a circuit breaker, getting the details right matters. The Q2125H is a 125-amp, 2-pole Type QPH circuit breaker with a plug-in design and a 120/240VAC rating. It carries a 22k AIC rating at 120/240VAC and is HACR-rated, so it can be used in compatible heating, air-conditioning, and refrigeration applications where these specifications are required. At 3.13 inches high, 2 inches wide, and 2.56 inches deep, it has a compact footprint that makes it easy to compare against an existing breaker. If you've landed here because Q2125H is the part number already in your equipment or documentation, the specifications below provide a quick way to check key details before making a replacement decision.

Material Compliance and Certifications

• Available specifications list the Q2125H as HACR-rated and rated at 40°C. Additional certification or material-compliance information has not been provided in the available product data. If a job requires a particular approval or compliance standard, verify that requirement using the breaker markings and appropriate technical documentation.

Where It Works Best

• The Q2125H makes sense for electrical work where the required specifications call for a 125A, 2-pole, Type QPH plug-in breaker operating at 120/240VAC. That can include compatible residential or commercial electrical distribution equipment, as well as qualifying HVAC applications where an HACR-rated breaker is specified.
