QBHW2125 - 125Amp Circuit Breaker

QBHW2125 - 125Amp Circuit Breaker

When you're replacing a circuit breaker, getting the details right matters. The QBHW2125 is a 125-amp, 2-pole bolt-on thermal magnetic circuit breaker rated 22k AIC at 120/240VAC. Part of the QBHW line, it provides thermal magnetic protection to help protect compatible electrical circuits from overload and short-circuit conditions. It's also Quicklag HACR rated and specified at 40°C, making it suitable for a range of compatible electrical distribution and HVAC applications. Size is another detail worth checking before making a match: the QBHW2125 measures approximately 3.41 inches high, 2 inches wide, and 2.92 inches deep. If you're replacing an existing breaker, don't rely on amperage alone. Check the QBHW type, 125A rating, two-pole configuration, 120/240VAC rating, 22k interrupting capacity, bolt-on connection, and physical dimensions against the equipment requirements. That extra check can save a lot of headaches later.

Key Features and Benefits

• 125-amp rating designed for applications requiring 125-amp circuit protection.
• Two-pole design provides two-pole protection in compatible electrical equipment.
• 22k AIC at 120/240VAC rated to interrupt up to 22,000 amps under its specified voltage conditions.
• Thermal magnetic operation provides protection against both overload and short-circuit conditions.
• Bolt-on configuration designed for a secure connection in compatible panels and distribution equipment.
• HACR rated, suitable for compatible heating, air-conditioning, and refrigeration applications where the specified breaker ratings are required.
• Breaker specifications are based on a 40°C ambient rating.
• Easy-to-check dimensions measure 3.41" H x 2.00" W x 2.92" D, helping you compare physical fit when replacing an existing breaker.

Material Compliance and Certifications

• Available specifications identify the QBHW2125 as HACR rated and specify a 40°C rating. No additional material-compliance or certification information was supplied for this particular breaker. Rather than assuming certifications that may not apply to every version, verify any required listing, certification, or material-compliance standard from the breaker nameplate or applicable manufacturer documentation.

Where It Works Best

• The QBHW2125 makes sense when the equipment specifically calls for a 125A, 2-pole QBHW bolt-on circuit breaker with a 120/240VAC rating and 22k AIC interrupting capacity. Typical applications may include compatible commercial electrical distribution systems, facility maintenance work, HVAC-related equipment, and replacement projects.
