Q1L2125 - 125 Amp Circuit Breaker

Q1L2125 - 125 Amp Circuit Breaker

If you're looking for a Q1L2125 circuit breaker, chances are you already have equipment that calls for this particular breaker style. The Q1L2125 is a 125-amp, 2-pole feed-through thermal-magnetic breaker, rated at 10k AIC at 120/240 VAC. It measures 6.38 inches high, 1.5 inches wide, and 2.31 inches deep, and it requires four spaces.

With older electrical equipment, replacing a breaker isn't simply a matter of finding another one with the same amp rating. The physical size, pole count, voltage, interrupting rating, and connection style all come into play. This Q1L model has a feed-through configuration and uses thermal-magnetic protection for overload and short-circuit conditions. For an existing installation that requires these specifications, it provides the form, fit, and function needed to keep the equipment in service.

The best approach is to compare the information on your existing breaker with the specifications below. Check the complete part number, not just the 125A marking. When the application calls for a Q1L2125, those small details can make a big difference in getting the correct fit. Properly installed and used within its stated ratings, this breaker is built to last.

Material Compliance and Certifications

• No specific material compliance declarations or agency certification details were provided in the available product information. If your application requires a particular certification or listing, confirm it with the breaker markings or the manufacturer's supporting documentation. UL, CSA, RoHS, or similar compliance should not be assumed unless it is documented for the specific breaker.

Where It Works Best

• The Q1L2125 is meant for electrical equipment designed around the Type Q1L feed-through breaker configuration. It is especially relevant for maintenance of legacy equipment where the goal is to match the existing breaker rather than change the system configuration.
