Multiquip 12SP37 Contactor CB-12

The Multiquip 12SP37 Contactor CB-12 is a genuine OEM Contactor CB-12 designed for the CB-12 control box. As a direct OEM replacement, the part is manufactured to the same specifications as the original component, ensuring a correct fit and consistent electrical performance within the control box assembly. This part is confirmed for use with CB-12 series control boxes, making it a straightforward replacement for technicians and operators servicing their submersible pump control systems.

Key Features

• Genuine OEM Electrical Specification — Matches the original contact rating, coil voltage, and switching capacity required by the CB-12 control box circuit.
• Direct-Fit Replacement — Installs into the CB-12 control box using the existing mounting points and wiring terminals, keeping service time short.
• CB-12 Compatibility Confirmed — Sourced and validated specifically for CB-12 series control boxes sold through the Multiquip submersible pump line.
• Sustained Switching Performance — A properly functioning contactor ensures the pump motor starts and stops cleanly under load; a worn or failed contactor can cause motor failure to engage or erratic cycling.
• Electrical Safety Integrity — Contactors carry high-current motor loads, and using a correctly rated OEM component helps prevent overheating, arcing, and potential damage to the control box and connected pump motor.

A contactor is an electrically controlled switch designed to handle the high current loads required to start and run a motor. Inside the CB-12 control box, it acts as the main switching element that connects and disconnects power to the submersible pump motor in response to control signals.
