Q1-330 - 30 Amp Circuit Breaker

Q1-330 - 30 Amp Circuit Breaker

When you're replacing a breaker in existing equipment, the details matter. The Q1-330 is a 30-amp, 3-pole Type Q1 circuit breaker with a plug-on design and thermal-magnetic operation. It is rated 10 kAIC at 240 VAC and measures 6.38 inches high, 2.25 inches wide, and 2.31 inches deep. This breaker also requires six spaces, an important detail to check when confirming fit in an existing installation. The Q1-330 is a good match for applications specifically designed around this breaker type, particularly when maintaining older or legacy electrical equipment where the correct physical size, mounting style, pole configuration, and electrical ratings need to be preserved. Simply put, if you're trying to replace an existing Q1-330, checking these specifications can help you avoid ending up with a breaker that looks similar but isn't right for the application. Designed for its intended electrical use and built to last, the Q1-330 provides the form, fit, and function needed in compatible equipment.

Material Compliance and Certifications

• Specific information regarding the materials, certifications, listings, or regulatory compliance of the Q1-330 was not provided. Any required certification should be confirmed using the markings found on the breaker itself and the applicable equipment or product documentation. Certifications such as UL, CSA, RoHS, or others should not be assumed unless they are specifically documented for the product.

Where It Works Best

• The Q1-330 circuit breaker is intended for compatible electrical equipment that calls for a Type Q1, 30-amp, 3-pole plug-on breaker with a 10 kAIC rating at 240 VAC. It is particularly relevant for maintenance and replacement situations involving existing or legacy equipment where matching the original breaker configuration is important.
• Before replacing a breaker, take a minute to compare the details—not just the part number. Check the amperage, number of poles, voltage and interrupting rating, mounting method, physical dimensions, and available spaces. For the Q1-330, that means 30 amps, three poles, 10k AIC at 240VAC, plug-on mounting, six spaces, and dimensions of 6.38" H x 2.25" W x 2.31" D.
• That careful match is what matters. The goal isn't to change the system; it's to find the correct form, fit, and functional replacement for equipment designed around this breaker configuration. Compatibility should be verified against the existing equipment and applicable documentation before installation.
