Q330H - 30Amp Circuit Breaker

Q330H - 30Amp Circuit Breaker

The Q330H circuit breaker is a 30-amp, 3-pole, Type QPH plug-in circuit breaker designed for 240VAC electrical applications that require dependable circuit protection and higher interrupting capacity. Rated at 22kA at 240VAC, the Q330H provides the interrupting performance needed to safely clear qualifying fault currents when properly applied within a compatible electrical system. Its three-pole configuration makes it a practical choice for appropriate multi-pole circuits, while the plug-in design supports straightforward installation in compatible load center equipment. The breaker carries a 30-amp rating at 40°C and is HACR-rated, making it suitable for installations of applicable heating, air-conditioning, and refrigeration equipment. With a compact footprint of approximately 3.13 inches high, 3.0 inches wide, and 2.56 inches deep, the Q330H delivers substantial protection without taking up unnecessary panel space. Whether you're replacing an existing compatible breaker or working with equipment that specifically calls for a Q330H, its clearly defined electrical ratings make it easier to verify that you're selecting the right circuit protection device for the job.

Key Features and Benefits

• 30-amp current rating provides circuit protection for compatible 30A electrical loads.
• 3-pole configuration designed to protect three conductors in an appropriate multi-pole application simultaneously.
• A 22 kA interrupting rating at 240 VAC provides 22,000 amps of fault-current protection for applications requiring this level of protection.
• Part of the QPH breaker family, helping technicians and facility personnel identify the correct breaker type for compatible equipment.
• Plug-in design allows the breaker to connect directly to compatible load center bus assemblies without a bolt-on mounting arrangement.
• HACR-rated, suitable for applicable heating, air-conditioning, and refrigeration equipment applications.
• The 30-amp current rating is specified at an ambient temperature of 40°C.
• Measuring approximately 3.13" H x 3.0" W x 2.56" D, the breaker provides its specified protection in a space-efficient package.

Material Compliance and Certifications

• The Q330H Type QPH circuit breaker is HACR rated for applicable heating, air-conditioning, and refrigeration applications. The QPH breaker family is manufactured to recognized circuit-breaker standards, including UL 489 and CSA C22.2 No. 5-16. Always confirm the markings and certifications on the individual breaker and verify compatibility with the intended panel or load center before installation.

Where It Works Best

• The Q330H 30A 3-pole circuit breaker is best suited for compatible 240VAC load center applications that require a Type QPH plug-in breaker with a 22kA interrupting rating. Its three-pole design makes it suitable for multi-pole electrical circuits, while the HACR rating supports applications involving heating, air-conditioning, and refrigeration equipment. It is also a strong choice for replacement situations where the existing equipment specifications specifically identify the Q330H or an electrically and mechanically compatible breaker.
