Multiquip 7128-07 Thermal Protector

The Multiquip 7128-07 is a genuine OEM Thermal Protector designed for Multiquip submersible pump models ST41230, ST41460, ST61230, and ST61460. Sourced directly from Multiquip, this part meets the exact specifications of the original component installed at the factory. It is a direct-fit replacement for the listed submersible pump models, ensuring correct installation without guesswork. When your pump's thermal protection system needs service, the 7128-07 is the correct part to restore proper function.

Key Features

• Genuine OEM Construction — Manufactured to the exact electrical and thermal tolerance specifications of the original part, ensuring the protection circuit responds accurately under load.
• Direct-Fit Replacement — Engineered to integrate with the motor winding circuit of the ST41230, ST41460, ST61230, and ST61460 exactly as the factory-installed component does.
• Broad Submersible Pump Compatibility — Confirmed fitment across both the ST4 and ST6 series Multiquip submersible pumps, covering multiple voltage configurations.
• Motor Overheating Defense — Automatically interrupts the motor circuit when internal temperatures exceed safe operating thresholds, protecting the motor windings from heat-related damage.
• Electrical Safety Function — As a critical protection component in the motor circuit, using a correctly rated thermal protector prevents uncontrolled overheating events that can damage the pump motor or create electrical hazards.

The thermal protector is a temperature-sensitive switch embedded in or connected to the pump motor's winding circuit. Its job is to monitor motor temperature during operation and automatically cut power if the motor begins to overheat — typically caused by running dry, excessive load, or blocked flow. Once the motor cools to a safe temperature, the protector resets and allows normal operation to resume. A failed or missing thermal protector leaves the motor with no overtemperature defense, which can result in burned windings, motor seizure, and costly pump failure.
