LB3125 - 125Amp Circuit Breaker Description
LB3125 - 125Amp Circuit Breaker
The LB3125 is a 125-amp, 3-pole Type LB circuit breaker with a thermal-magnetic design and an interchangeable trip unit. It is rated for 40°C and comes with load-side terminals. On the electrical side, it has interrupting ratings of 22kA at 600VAC, 30kA at 480VAC, and 42kA at 240VAC. You'll want the Type LB configuration, amperage, pole count, voltage, AIC ratings, trip arrangement, terminals, and physical size to match the existing installation requirements.

Material Compliance and Certifications
No specific UL, CSA, IEC, RoHS, REACH, or other certification or material-compliance information was provided for the LB3125. Because of that, don't assume those credentials based on the LB designation or the specifications of other breakers in the same general product family.
Where It Works Best
The LB3125 makes the most sense when you're maintaining equipment that specifically calls for a 125A, 3-pole Type LB thermal-magnetic breaker with an interchangeable trip unit. That can be particularly useful when working with existing or legacy electrical systems where maintaining the correct form, fit, and function is the priority.
Compare the electrical ratings first. Depending on system voltage, this breaker carries an interrupting rating of 22kA at 600VAC, 30kA at 480VAC, or 42kA at 240VAC. The 40°C rating and interchangeable trip configuration must also suit the application.
