Q2125BHH - 125Amp Circuit Breaker

Q2125BHH - 125Amp Circuit Breaker

When you're matching a circuit breaker to an existing electrical system, the details count. The Q2125BHH is a 125-amp, 2-pole HQPP circuit breaker with a 65 kA A.I.C. rating at 120/240 VAC. It uses a thermal-magnetic trip mechanism, giving the breaker two forms of response: thermal protection for sustained overload conditions and magnetic response when a short circuit occurs. This model has a plug-in connection and requires at least four panel spaces, so it's important to check available space and equipment compatibility beforehand. Measuring 4.5 inches high, 4.0 inches wide, and 2.56 inches deep, the Q2125BHH is a practical option when these specific electrical and physical characteristics are called for. Before replacing an existing breaker, compare the complete specifications, not just the amperage or part number, to make sure you have the right match for the application.

Key Features and Benefits

• 125-amp rating for applications that specifically call for 125A circuit protection.
• 2-pole configuration for compatible 120/240VAC electrical systems.
• 65 kA A.I.C. at 120/240 VAC provides the specified short-circuit interrupting capacity.
• Thermal-magnetic trip responds to both sustained overloads and short-circuit conditions.
• Plug-in connection for use in compatible electrical distribution equipment.
• HQPP type makes it easy to compare against the requirements of an existing installation.
• Requires a minimum of four panel spaces, an important detail to check before installation.

Material Compliance and Certifications

• Certification and material-compliance requirements can vary by application, project, and electrical system. For that reason, specific certifications or compliance claims shouldn't be assumed without supporting product documentation. Check the markings on the individual Q2125BHH breaker and the applicable manufacturer documentation when a particular listing, certification, or material standard is required.

Where It Works Best

• The Q2125BHH circuit breaker is best suited for compatible electrical distribution equipment that calls for an HQPP plug-in breaker with a 125A rating, two poles, 120/240VAC operation, and 65kA interrupting capacity.
  
  It's a useful match for electricians, contractors, maintenance departments, and facility teams replacing an existing breaker or working from an electrical specification. And while matching the Q2125BHH part number is a good starting point, don't stop there. Check the voltage, amperage, poles, A.I.C. rating, connection style, dimensions, and four-space requirement as well.
