Q1-320 - 20 Amp Circuit Breaker

Q1-320 - 20 Amp Circuit Breaker

When an existing electrical setup calls for a Q1-320, matching the details is what matters. This is a 20-amp, 3-pole Type Q1 circuit breaker with a plug-on connection and thermal-magnetic operation. Its electrical rating is 10 kAIC at 240 VAC. The breaker measures 6.38 inches high, 2.25 inches wide, and 2.31 inches deep, and you'll need six spaces for the installation. Those details are worth checking carefully, especially when you're working with older equipment where simply finding another 20-amp breaker isn't enough. The mounting style, number of poles, voltage, interrupting rating, dimensions, and available space all play a part in getting the right fit. For compatible legacy equipment designed around the Type Q1 configuration, the Q1-320 provides a practical way to maintain the original form, fit, and function. It's built to last and intended for use within its specified electrical ratings.

Key Features and Benefits

• 20-amp, 3-pole design for equipment that requires this configuration.
• Type Q1 construction for use with compatible electrical equipment.
• Plug-on connection makes it suitable for applications designed for this mounting arrangement.
• Thermal magnetic operation provides circuit protection against overload and overcurrent conditions.
• Rated 10 kA at 240VAC.
• Requires six spaces, so available space should be checked as part of the compatibility review.
• Measures 6.38" H x 2.25" W x 2.31" D.
• A useful option for maintaining legacy electrical systems that were designed for this breaker type.

If a particular certification, listing, or material requirement applies to the job, verify it using the product labeling and applicable technical documentation before installation.

Where It Works Best

• The Q1-320 is intended for compatible equipment that calls for a Type Q1, 20-amp, 3-pole plug-on thermal-magnetic breaker. It's especially relevant when servicing an older electrical installation and the goal is to keep the existing equipment configuration intact rather than change it.
• Don't go by amperage alone when checking a replacement. Compare the existing application with the Q1-320's three-pole configuration, 240 VAC rating, 10 kAIC rating, plug-on mounting style, six-space requirement, and physical dimensions. Getting those details right is far more useful than choosing a breaker simply because it looks similar.
• As with any circuit breaker replacement, confirm that the Q1-320 is suitable for the specific equipment before installation. Installation should be completed by a qualified electrical professional in accordance with applicable electrical codes and equipment requirements.
