Q2125BH - 125Amp Circuit Breaker

Q2125BH - 125Amp Circuit Breaker

Suppose you're replacing a Q2125BH circuit breaker; getting the details right matters. This is a 125-amp, 2-pole, Type QPPH breaker rated for 120/240 VAC, with a 22 kAIC rating. It uses a plug-in connection and thermal-magnetic trip operation to protect against both overload and short-circuit conditions in compatible electrical equipment.

One thing to keep in mind is space. The Q2125BH requires a minimum of four panel spaces, so it's worth checking your panel before installation. The breaker measures 4.5 inches high, 4 inches wide, and 2.56 inches deep. For replacement work, compare more than just the amperage. The part number, QPPH type, two-pole configuration, voltage, AIC rating, mounting style, dimensions, and panel requirements should all match the intended application.

Key Features and Benefits

• 125-amp rating for applications requiring this specific current rating.
• 2-pole design for compatible 120/240VAC electrical systems.
• 22k AIC at 120/240VAC provides the specified interrupting capacity.
• Thermal-magnetic trip responds to overload and short-circuit conditions.
• Plug-in configuration for use with compatible equipment.
• Type QPPH construction makes it easier to identify and compare with an existing breaker.
• Requires a minimum of four panel spaces, an important detail to check before installation.

Material Compliance and Certifications

• Material compliance and certification information is not included in the available specifications for the Q2125BH. If your project requires a particular listing, certification, or material standard, check the markings on the breaker and the appropriate product documentation before installation.

Where It Works Best

• The Q2125BH is a practical choice for replacement and maintenance applications where the existing electrical equipment calls for a 125A, 2-pole, Type QPPH plug-in breaker rated 22k AIC at 120/240VAC. It's also useful when servicing existing distribution equipment and an exact match to these electrical and physical specifications is required.
