The LB2125 is a Leviton LB212-series 2-pole, 125A, 240V plug-in breaker designed for use in Leviton LB-series loadcentres and panelboards that accept the LB212 plug-in format. It is suited for both residential and light commercial installations where a 10kA interrupting rating meets the available fault current at the panel. This breaker is not interchangeable with other manufacturers' plug-in breakers (e.g., Siemens QP, Square D QO, Eaton BR). Send us your panel model and we'll confirm fitment before you order.
The LB2125 is designed for Leviton LB-series loadcentres and panelboards that accept LB212 plug-in breakers. It is not cross-compatible with other brands' panels. If you're unsure whether your panel accepts this breaker, contact us with your panel model number and we'll confirm compatibility for you.
For most residential and light commercial applications in Canada, a 10kA interrupting rating is typically adequate — especially on branch or feeder circuits where the available fault current is at or below 10kA. However, you should verify the available short-circuit current at the panel with your electrical engineer or authority having jurisdiction (AHJ) to ensure compliance with the Canadian Electrical Code (CEC).
