HQJ22B125H - 125Amp Circuit Breaker

HQJ22B125H - 125Amp Circuit Breaker

When you're replacing a breaker in existing electrical equipment, the details have to line up—not just the amperage. The HQJ22B125H circuit breaker is a 125-amp, 2-pole molded-case circuit breaker with a 100k AIC rating at 240 VAC. For legacy systems that specifically require this combination of form, fit, and electrical ratings, the HQJ22B125H offers a clear replacement option. It's built to last, while proper selection still comes down to matching the complete specification—not simply finding another 125A breaker.

Key Features and Benefits

• 125-amp rating: Provides the specified 125A current rating for compatible electrical equipment.
• 2-pole configuration: Suitable for applications requiring a two-pole molded-case circuit breaker.
• HQJ2H type: Helps identify the correct breaker family when matching an existing installation.
• HACR rated: Suitable where an HACR-rated breaker is specifically required, and the remaining electrical specifications are compatible.
• 40°C rating: Provides an important temperature rating to check against equipment and installation requirements.
• Molded-case construction: Matches equipment designed around this circuit-breaker format.
• Load-side lugs included: The supplied configuration includes load-side lugs, an important detail when confirming connection requirements.

Material Compliance and Certifications

The available specifications identify the HQJ22B125H as HACR rated. No additional agency certifications or material-compliance declarations were provided in the supplied product data. For that reason, certifications or declarations such as UL, CSA, RoHS, or REACH should not be assumed without supporting manufacturer documentation or markings on the breaker.

Where It Works Best

The HQJ22B125H 125A circuit breaker makes sense for compatible existing and legacy electrical equipment that calls for its specific combination of a 125A rating, two poles, HQJ2H type, 100k AIC at 240VAC, 40°C rating, HACR rating, molded case construction, and load-side lug configuration. Its stated dimensions should also be carefully checked when matching to an existing breaker.
