QBHW3020H - 20Amp Circuit Breaker

QBHW3020H - 20Amp Circuit Breaker

The QBHW3020H is a 20-amp, 3-pole Quicklag Type QBHW circuit breaker designed for use in your compatible electrical distribution equipment. It uses a bolt-on connection and thermal-magnetic trip design, providing protection against both overloads and short-circuit conditions. Rated 22 kAIC at 240VAC, this breaker is a good fit for your applications where the available fault current calls for that interrupting capacity. It is also HACR rated and has a 40°C rating, which makes it suitable for qualifying heating, air-conditioning, and refrigeration applications when the equipment and circuit specifications call for these ratings. With three poles and a 20A rating, the QBHW3020H can be used in compatible commercial and industrial electrical systems where a Type QBHW bolt-on breaker is required. Before installation, always confirm the complete part number, breaker type, voltage, amperage, interrupting rating, and panel compatibility—not just the physical size.

Key Features and Benefits

• 20A rating for circuits requiring 20-amp protection.
• Three-pole design for compatible three-pole applications.
• 22 kAIC at 240VAC provides the specified interrupting capacity for higher available fault-current applications.
• Thermal-magnetic trip mechanism responds to overload and short-circuit conditions.
• Bolt-on construction creates a secure connection in compatible electrical equipment.
• Quicklag Type QBHW design makes breaker-family identification straightforward when checking compatibility.
• HACR rated for qualifying heating, air-conditioning, and refrigeration applications.
• 40°C rated for its specified operating characteristics.

Material Compliance and Certifications

• The QBHW3020H is associated with established circuit-breaker safety standards and certification requirements. Because certification and material-compliance documentation can vary by product revision and manufacturing date, any project that requires a particular UL, CSA, RoHS, or other compliance designation should have that requirement confirmed against the product label and current manufacturer documentation. This is especially important for installations governed by project-specific specifications or electrical codes.

Where It Works Best

• The QBHW3020H is best suited to compatible panelboards and electrical distribution equipment designed to accept Type QBHW bolt-on circuit breakers. Typical applications may include commercial buildings, industrial facilities, mechanical equipment, and qualifying HVAC or refrigeration circuits. Its 20A rating, three-pole configuration, 240VAC rating, and 22 kAIC interrupting capacity need to match the requirements of the electrical system.
• If you’re replacing an existing breaker, QBHW3020H should be matched by the complete part number and electrical specifications rather than appearance alone. Similar-looking breakers can have different mounting arrangements, interrupting ratings, or application requirements.
