MBKQR1 – SIEMENS MAIN/SUB BREAKER KIT 2 POLE P1 PANEL

When configured as a main breaker, the SIEMBKQR1 provides the primary overcurrent disconnect at the top of the P1 panel, controlling all branch circuits. When used as a sub-panel kit, it allows the panel to receive power from an upstream main panel, with the breaker acting as the feeder disconnect. The SIEMBKQR1 kit includes the hardware to support both configurations — your specific wiring and labelling requirements will differ between the two setups, so consult a licensed electrician to ensure your installation meets Canadian Electrical Code (CEC) requirements.

The SIEMBKQR1 is a kit that typically includes the 2-pole breaker and mounting hardware required for the P1 panel configuration. However, you may still need appropriate conductors, lugs, and a neutral/ground bar depending on your panel's existing setup and whether you're wiring it as a main or sub-panel. We recommend confirming your full parts list with our counter staff or a qualified electrician before beginning installation.
