Q2L2125 - 125 Amp Circuit Breaker

Q2L2125 - 125 Amp Circuit Breaker

Need to replace a Q2L2125 circuit breaker in existing equipment? This 125-amp, 2-pole thermal magnetic breaker is intended for compatible 120/240VAC applications and carries a 10 kA.I.C. rating. It uses a non-interchangeable trip unit and has lug terminals on both the line and load sides. The breaker measures 6.5 inches high, 3 inches wide, and 3.13 inches deep, which gives you another important reference point when checking fit. For equipment originally using the Q2L2125, a new-style breaker from the same manufacturer is supplied and is specifically designed to serve as its replacement. This makes it a sensible option for maintaining legacy equipment where the original electrical ratings, connection style, and physical configuration need to be matched. It's a straightforward replacement solution that's built to last and made for the job it was designed to do.

Key Features and Benefits

• 125-amp, 2-pole design for compatible electrical applications.
• 120/240VAC rating with a 10k A.I.C. interrupting rating.

Material Compliance and Certifications

• Specific material compliance information and certification details were not included with the available Q2L2125 specifications. If your installation has particular listing, certification, or material requirements, confirm those details using the manufacturer's documentation and the markings on the breaker itself. This is especially important for applications that must meet specific electrical codes or project requirements.
  

Where It Works Best

• The Q2L2125 125A 2-pole breaker is a good fit for compatible legacy electrical systems that were designed around this breaker configuration. It's particularly relevant when you're trying to match a 125-amp rating, two poles, 120/240VAC operation, 10k A.I.C., and line-and-load lug connections without changing the intended function of the equipment.
