Q330 - 30Amp Circuit Breaker

Q330 - 30Amp Circuit Breaker

Need a 30-amp, 3-pole circuit breaker for a compatible Type QP application? The Q330 circuit breaker provides the key ratings you need in a compact, plug-in design that's easy to identify and match with the right electrical equipment. This Type QP breaker is rated for 30 amps, features three poles, and carries a 10 kA interrupting rating at 240 VAC. It's also HACR-rated, making it suitable for compatible heating, air-conditioning, and refrigeration applications when the equipment specifications call for these ratings. Measuring approximately 2.88 inches high, 3.0 inches wide, and 2.56 inches deep, the Q330 offers a space-conscious solution for electrical distribution and replacement applications. Whether you're replacing an existing Q330 or matching a breaker to compatible equipment, the important thing is getting the specifications right, and this breaker gives you a straightforward combination of 30A capacity, three-pole protection, Type QP plug-in construction, and a 240VAC rating.

Key Features and Benefits

• Designed for circuits requiring a 30A circuit breaker.
• Three-pole configuration makes the Q330 suitable for compatible multi-pole electrical applications.
• Designed for use in electrical equipment specifically compatible with Type QP plug-in circuit breakers.
• The plug-in configuration makes the breaker a practical choice for compatible panel and load center applications.
• 10kA AIC at 240VAC, rated to interrupt up to 10,000 amps of fault current at 240VAC under its specified conditions.
• HACR-Rated, suitable for compatible heating, air-conditioning, and refrigeration applications where an HACR-rated breaker with these electrical specifications is required.
• Rated based on a 40°C (104°F) ambient temperature.
• Measures approximately 2.88" H × 3.0" W × 2.56" D, making its physical dimensions easy to verify when matching an existing breaker.

Material Compliance and Certifications

• The Q330 circuit breaker is HACR-rated and has a specified ambient temperature rating of 40 °C. Because certifications, listings, labeling, and material-compliance requirements may vary by individual breaker, production version, and application, always verify the markings on the breaker itself when a particular certification or compliance requirement is required.

Where It Works Best

• The Q330 30-amp 3-pole Type QP circuit breaker is a strong fit for maintenance, replacement, and electrical distribution applications, as it is specifically designed for a compatible Type QP plug-in breaker. It's especially useful when you need a breaker combining 30A capacity, three poles, 240VAC operation, and a 10kA AIC rating in one compact package.
  
• It can also be used in compatible heating, air-conditioning, and refrigeration applications where an HACR-rated breaker with these specifications is called for. Replacing an existing breaker? Matching the Q330 part number is a useful starting point, but don't stop there. Check the amperage, number of poles, voltage, interrupting rating, breaker type, physical fit, and the electrical equipment's labeling before installation.
