QBHW3030H - 30Amp Circuit Breaker

QBHW3030H - 30Amp Circuit Breaker

The QBHW3030H circuit breaker is a 30-amp, 3-pole, bolt-on thermal magnetic circuit breaker designed for dependable circuit protection in compatible electrical distribution applications. Part of the QBHW type, this breaker combines a 30A current rating with a 22kA A.I.C. rating at 240VAC, making it a practical choice when your application calls for a compact three-pole breaker with substantial interrupting capacity. Its thermal magnetic trip mechanism provides circuit protection against overload and short-circuit conditions, while the bolt-on configuration provides a secure connection within compatible equipment. The QBHW3030H is also HACR rated and carries a 40°C rating, adding versatility for appropriate heating, air-conditioning, refrigeration, and other electrical applications. Measuring approximately 3.41 inches high, 3.0 inches wide, and 2.92 inches deep, this breaker offers useful protection without taking up unnecessary space. When you're replacing an existing breaker, always confirm the part number, electrical ratings, physical dimensions, connection style, and equipment compatibility before installation.

Key Features and Benefits

• Provides 30A circuit protection for compatible electrical loads and equipment.
• Designed for applications requiring simultaneous protection across three poles.
• 22kA A.I.C. at 240VAC offers an interrupting rating of 22,000 amps at 240 volts AC.
• Thermal magnetic protection helps protect electrical circuits against both sustained overload conditions and short circuits.
• Bolt-on design creates a secure mechanical and electrical connection in equipment designed to accept this breaker configuration.
• HACR rated, suitable for compatible heating, air-conditioning, and refrigeration applications when all system requirements are met.
• Rated with a 40°C ambient temperature reference.
• Its 3.41" x 3.0" x 2.92" size makes it easy to compare against an existing breaker or available equipment space.
• Clearly identified as a QBHW-series breaker for easier specification matching and replacement identification.

Material Compliance and Certifications

• The available specifications identify the QBHW3030H as HACR rated and specify a 40°C rating. No additional material-compliance designations or certifications are included in the supplied product data. For projects requiring specific regulatory, environmental, material, or certification documentation, those requirements should be verified against the breaker itself and applicable manufacturer documentation before installation.

Where It Works Best

• The QBHW3030H 30 amp 3-pole circuit breaker is best suited to compatible electrical distribution equipment requiring a three-pole, 30A bolt-on thermal magnetic breaker with a 22kA interrupting rating at 240VAC. Its HACR rating also makes it a potential fit for compatible heating, air-conditioning, and refrigeration equipment where the electrical system specifically calls for an HACR-rated breaker with these characteristics.
  
  It can be especially useful when replacing an existing QBHW3030H or when a project specification calls for the same electrical ratings, pole configuration, mounting style, and physical dimensions. Because circuit breakers are safety-critical components, matching amperage alone is not enough. Confirm the QBHW type, 30-amp rating, three-pole configuration, 240VAC application requirements, 22kA A.I.C. rating, bolt-on connection, dimensions, and equipment compatibility before installation. Installation and application should follow applicable electrical codes and be performed by qualified personnel.
