Q1-2125 - 125 Amp Circuit Breaker

Q1-2125 - 125 Amp Circuit Breaker

Need a Q1-2125 circuit breaker for an existing electrical system? This 125-amp, 2-pole Type Q1 breaker is a plug-on thermal-magnetic circuit breaker rated at 10 kAIC at 120/240 VAC. It requires four spaces and measures 6.38 inches high, 1.5 inches wide, and 2.31 inches deep. Those details are worth checking carefully, especially when you're replacing a breaker in older or legacy equipment, where the physical fit and electrical ratings must match the original application. The thermal-magnetic design protects against both overload and short-circuit conditions. For anyone maintaining equipment that calls for the Q1 configuration, the Q1-2125 offers the specific form, fit, and function needed for the intended system. It's built to last when installed correctly and used within its specified ratings. Before replacing an existing breaker, compare the part number and specifications with the equipment documentation to make sure everything matches.

Material Compliance and Certifications

• Material compliance and certification information was not provided with the available specifications for the Q1-2125. Check the markings on the breaker and the documentation for the electrical equipment to confirm any certifications, listings, or compliance requirements needed for your particular application.

Where It Works Best

• The Q1-2125 makes the most sense in existing or legacy electrical equipment designed for Type Q1 plug-on circuit breakers. It's intended for applications requiring a 125-amp, 2-pole breaker rated for 120/240 VAC with a 10 kA.I.C. rating.
  
• When you're matching a circuit breaker, amperage is only part of the picture. Check the breaker type, number of poles, voltage, interrupting rating, mounting style, dimensions, and required panel space as well. If you're replacing an existing Q1-2125, comparing these specifications with the original breaker and equipment documentation is the simplest way to verify that the breaker is right for the application.
