Q1-2100 - 100 Amp Circuit Breaker

Q1-2100 - 100 Amp Circuit Breaker

If you're working on an existing electrical system that calls for a Q1-2100, it's important to match the breaker to the original application. The Q1-2100 is a 100-amp, 2-pole Type Q1 plug-on thermal-magnetic circuit breaker with a 10 kA I.C. rating at 120/240 VAC. It measures 6.38 inches high, 1.5 inches wide, and 2.31 inches deep and requires four spaces. This breaker is a practical choice for maintenance and replacement work in compatible legacy equipment that requires the correct Type Q1 design, electrical ratings, dimensions, and plug-on connection. Its thermal magnetic trip mechanism provides overcurrent protection for the circuit when used within its specified ratings. When replacing an existing breaker, don't rely on amperage alone—the mounting style, number of poles, voltage, interrupting rating, dimensions, and available panel space must all match the application. For systems specifically designed around the Q1-2100 configuration, this breaker provides the form, fit, and function needed to keep existing equipment in service. It's a straightforward replacement component built to last when correctly selected and installed.

Key Features and Benefits

• 100-amp capacity for applications designed around this specific current rating.
• 2-pole configuration for compatible two-pole circuits.
• Type Q1 design helps match the form and fit required by compatible existing equipment.
• Plug-on mounting provides the connection style used by the intended electrical assembly.
• Thermal-magnetic trip mechanism provides overcurrent protection within the breaker's rated application.
• 10 kA I.C. at 120/240VAC gives you a clearly defined interrupting and voltage rating to check against the existing system.
• Four-space design makes panel-space verification an important part of the fit confirmation process.
• Well suited to maintenance and replacement work in compatible legacy electrical systems.

Material Compliance and Certifications

• Material compliance and certification details are not specified in the available product information for the Q1-2100, so no particular certification or listing should be assumed. Check the markings on the breaker and the requirements of the electrical equipment before installation.
• As with any circuit breaker replacement, the product should be used only in equipment where its ratings and configuration are appropriate. Installation should be handled by qualified personnel and completed in accordance with applicable electrical codes and local requirements.

Where It Works Best

• The Q1-2100 is best suited to existing and legacy electrical systems that were designed for the Type Q1 plug-on breaker configuration. It can be especially useful during maintenance or repair work when the goal is to replace an existing breaker while maintaining the required form, fit, and electrical function.
