The Multiquip CB12SP37 Contactor CB-12 14 is a genuine OEM contactor designed for the Multiquip CB-12 submersible pump control box. This is a direct OEM replacement sourced from Multiquip, ensuring the component meets the original electrical specifications required for proper control box operation. Verified to fit the CB-12 series, the part is the correct replacement when the existing contactor shows signs of wear, failure to engage, or electrical faults.
Key Features
- Genuine OEM Electrical Spec — Built to the original contact rating and coil voltage specification, ensuring proper switching performance in the CB-12 control circuit.
- Direct Drop-In Replacement — Matches the original mounting configuration and terminal layout of the CB-12 control box for a straightforward swap.
- CB-12 Series Fitment — Confirmed fit for Multiquip CB-12 submersible pump control boxes.
- Restores Reliable Pump Switching — A worn or failed contactor can prevent the pump motor from starting or cause erratic cycling; replacing it with the correct OEM part restores consistent, controlled pump operation.
- Electrical Safety Compliance — Using the correct OEM-rated contactor in a motor control circuit is critical to preventing overload faults, arcing, and potential motor damage.
A contactor is an electrically controlled switch used within the control box to start and stop the submersible pump motor. When the control signal is received, the contactor closes its power contacts to energize the motor, and opens them again to shut it down safely. When a contactor wears out or fails, the pump may refuse to start, run continuously without shutting off, or trip breakers due to improper contact closure — all of which interrupt pump operation and can cause downstream damage to the motor.
