The Honda 369450508 Thermal Protector is a genuine OEM component designed for WSP50 and WSP100 submersible electric water pumps. As a direct OEM replacement, this part is built to Honda's original specifications, ensuring it integrates correctly with the pump's electrical system. Buyers should confirm their pump model and serial number against the fitment table before ordering, as Honda periodically supersedes parts at production breaks.
Key Features
- Genuine OEM Protection — sourced directly from Honda, this thermal protector matches the original component's electrical ratings and trip characteristics for the WSP50 and WSP100.
- Direct OEM Replacement — replaces the original part with no modification to the pump's wiring or housing required, restoring the pump's built-in overload protection.
- Submersible Pump Fitment — engineered specifically for the WSP50 and WSP100 submersible electric water pumps; verify your model against the fitment table to confirm compatibility.
- Serial Number Verification Recommended — Honda supersedes parts at production breaks, so check your pump's serial number against the fitment table to ensure this is the correct thermal protector for your unit.
A thermal protector is an automatic safety device built into the WSP50 and WSP100 submersible electric water pumps to guard the sealed electric motor against dangerous overheating. When the motor draws excessive current — due to a blocked intake, a dry run, or an electrical fault — the protector interrupts power before heat can damage the motor windings. Once the motor cools to a safe temperature, the device resets and allows the pump to resume normal operation. A failed or missing thermal protector leaves the motor vulnerable to burnout, turning a minor fault into a costly repair.
