The Multiquip 0201503UL446 Auto-Cut Protector is a genuine OEM component designed for the ST-1500 clean water submersible pump. As an authorized Multiquip replacement part, the part is built to the same specification as the original, ensuring it integrates correctly with the pump's electrical protection system. Sourced directly through Multiquip's OEM supply chain, this part is the verified replacement for ST-1500 applications. If your submersible pump is tripping, failing to restart, or showing signs of thermal overload, this is the component to inspect and replace.
Key Features
- Thermal Overload Protection: — Engineered to interrupt power at precise overload thresholds, protecting the pump motor from heat-related damage that leads to costly motor failure.
- Genuine OEM Construction: — Manufactured to Multiquip's original electrical specification, including correct trip rating and terminal configuration for the ST-1500 pump's protection circuit.
- Direct Drop-In Replacement: — Matches the mounting footprint and wiring connections of the original protector, allowing straightforward field replacement without circuit modification.
- ST-1500 Submersible Pump Fitment: — Confirmed fit for the Multiquip ST-1500 clean water submersible pump series — use part number 0201503UL446 when ordering to ensure the correct unit.
- Electrical Safety Compliance: — As a protective device within the pump's electrical system, using the correct OEM-spec protector maintains the intended safety envelope of the pump under load and thermal stress conditions.
The Auto-Cut Protector is a thermally activated safety device built into the electrical circuit of the submersible pump motor. Its role is to detect abnormal heat buildup or electrical overload and automatically cut power to the motor before damage can occur, then reset once the motor cools to a safe operating temperature. When this protector fails or degrades, the pump may shut off unexpectedly, refuse to restart, or — in the absence of any protection — continue running under overload conditions until the motor windings burn out entirely.
