The Multiquip EM97050 Small Relay is a genuine OEM electrical relay designed for ST-45HRM and ST-70 submersible pumps. As a direct Multiquip OEM component, it is manufactured to the same specifications as the original part, ensuring correct operation within your pump's electrical control circuit. This relay is the exact unit specified for ST-45HRM and ST-70 models, so you can install with confidence knowing the fit and function match what came from the factory.
Key Features
- OEM-Matched Electrical Specification — Built to the correct coil resistance and contact rating for the ST-45HRM and ST-70 submersible pump control circuits, not a generic substitute.
- Drop-In Replacement — Connects directly to the existing wiring harness using the original mounting position, requiring no adaptation of connectors or brackets.
- Confirmed Fitment — Verified for ST-45HRM and ST-70 series submersible pumps; check your model code before ordering to ensure compatibility.
- Protects Downstream Components — A correctly functioning relay switches high-current pump loads without exposing control-side wiring to damaging amperage, preserving the integrity of the broader electrical system.
- Electrical Safety Compliance — As a genuine OEM relay, this component meets the original design intent for current switching in a wet-environment pump application, where undersized or incorrect relays pose a real risk of overheating or failure.
A relay is an electrically operated switch that uses a low-power control signal to open or close a higher-power circuit. In a submersible pump, the small relay typically manages the switching of the pump motor or a key control function — allowing the system's logic or float switch to trigger pump operation without routing full motor current through sensitive control wiring. When a relay fails, the pump may refuse to start, run continuously without shutting off, or behave erratically, making it one of the first components to inspect during an electrical fault diagnosis.
