QBHW1020 - 20 Amp Circuit Breaker

QBHW1020 - 20 Amp Circuit Breaker

When you're replacing a circuit breaker, getting the details right matters. The QBHW1020 is a 20-amp, single-pole thermal-magnetic circuit breaker with a bolt-on connection and a 22kA A.I.C. rating at 120VAC. It's part of the QBHW Quicklag line and is HACR rated, so it can be used in compatible heating, air-conditioning, and refrigeration applications where these specifications are required. The thermal-magnetic design protects against both overloads and short circuits, while the bolt-on mounting style ensures a secure connection in equipment that accepts it. Size is another important consideration when you're matching a replacement: this breaker measures 3.41 inches high, 1 inch wide, and 2.92 inches deep. It also carries a 40°C rating. If you're replacing an existing breaker, compare more than just the 20-amp rating. Check the QBHW1020 part number, pole count, voltage, interrupting rating, mounting style, and dimensions to ensure they align with the requirements of your panel or equipment.

Key Features and Benefits

• 20-amp, single-pole design for compatible 120VAC applications.
• 22kA interrupting rating at 120VAC for the specified level of fault-current protection.
• Thermal-magnetic operation helps protect against sustained overloads and short-circuit conditions.
• A bolt-on connection provides a secure mounting method for compatible electrical equipment.
• HACR rated for appropriate heating, air-conditioning, and refrigeration applications.
• 40°C, rated per the available product specifications.
• The compact 1-inch width makes it easy to compare with the physical requirements of an existing installation.
• QBHW Quicklag type helps identify the breaker when matching an existing component.

Where It Works Best

• The QBHW1020 makes sense when the job calls for a 20A, 1-pole, 120VAC bolt-on breaker with a 22kA A.I.C. rating and the equipment is designed for the QBHW breaker type. It can be used in compatible general electrical distribution applications and, thanks to its HACR rating, in appropriate heating, air-conditioning, and refrigeration equipment.
