Q1-240 - 40 Amp Circuit Breaker

Q1-240 - 40 Amp Circuit Breaker

Looking for a Q1-240 circuit breaker to match an existing installation? This Type Q1, 40-Amp, 2-pole breaker is designed for compatible electrical equipment that uses this specific plug-on configuration. It features thermal-magnetic operation and is rated at 10 kA I.C. at 120/240 VAC. For maintenance work on older electrical systems, details matter—the breaker has to match the equipment, not just the amperage. The Q1-240 measures 6.38 inches high, 1.5 inches wide, and 2.31 inches deep, and it requires four spaces. That makes checking the existing breaker, panel requirements, and available space an important part of determining fit. If your equipment specifically calls for the Q1-240 or a breaker with these matching characteristics, this unit provides the form, fit, and function needed for the intended application. It’s a straightforward, built-to-last component for keeping compatible legacy electrical equipment in service.

Material Compliance and Certifications

• Material compliance and certification details were not provided for the Q1-240. If your installation requires a specific certification, listing, or material compliance standard, check the markings on the breaker and the appropriate product documentation before installation. No UL, CSA, RoHS, or other certification should be assumed unless it is specifically documented for the product.

Where It Works Best

• The Q1-240 40-Amp 2-pole circuit breaker is best suited to existing electrical equipment designed around the Type Q1 plug-on breaker configuration. It can be a good fit for maintenance and repair jobs where the goal is to keep the original system configuration.
• Before using it as a replacement, compare more than the part number. Check the 40-Amp rating, two-pole configuration, 120/240 VAC voltage rating,10 kA I.C. rating, four-space requirement, physical dimensions, and Type Q1 configuration against the equipment requirements.
• When those details line up, you have a much clearer picture of whether the Q1-240 is the right fit for the job. As with any circuit breaker replacement, compatibility should be confirmed before installation, and the work should follow applicable electrical codes and equipment requirements.
