LA3125 - 125Amp Circuit Breaker

LA3125 - 125Amp Circuit Breaker

The LA3125 is a 125-amp, 3-pole Type LA circuit breaker for electrical systems that require this specific combination of size, rating, and configuration. If you're matching an existing breaker, it pays to look at the whole unit, not just amperage. When those details match the equipment requirements, this breaker is well suited as a form, fit, and functional replacement in compatible existing and legacy systems. Properly selected, installed, and kept within its specified ratings, the LA3125 is built to last.

Where It Works Best

The LA3125 makes the most sense in existing or legacy electrical equipment that calls for a 125-amp, 3-pole Type LA thermal magnetic circuit breaker with an interchangeable trip unit. For maintenance and replacement work, the correct catalog number helps, but the application requirements should make the final call.
