The LM125 – Leviton 2P 125A 240V Push-In Main Breaker is designed for reliable circuit protection with a 22kA interrupting capacity. Ideal for residential and commercial applications, it ensures safety and compliance. The push-in design simplifies installation, making it a perfect choice for efficient power management in your electrical systems.
The LM125 is designed for Leviton loadcentres that accept the LM-series plug-in main breaker. Because main breaker fitment is panel-specific, we recommend confirming your panel's model number with us before ordering — contact our counter staff in Calgary, Edmonton, or Vancouver and we'll verify compatibility for you.
The LM125 is specifically rated and configured as a main breaker (main disconnect) for a loadcentre or panelboard. It should not be used as a standard branch-circuit breaker. Its 125A rating defines the maximum service capacity for the panel it protects.
A 22kA interrupting capacity meets the fault-current levels found in most Canadian residential services and many light commercial applications. However, you should always verify the available fault current at your panel location — typically provided by your utility or confirmed through a short-circuit study — to ensure the breaker's interrupting rating equals or exceeds that value, as required by the Canadian Electrical Code (CEC).
