The Multiquip Y0602201457 Heater Relay is a genuine OEM component designed for DCA-series Super-Silent diesel generators including the DCA150SSCU4i, DCA220SSCU, DCA220SSCU4I, DCA300SSCU2, and DCA300SSCU4i. As a direct OEM replacement, this relay is built to the same specifications as the original part, ensuring consistent electrical performance across the heater circuit. Sourced directly through authorized Multiquip supply channels, Y0602201457 is the correct part to restore proper heater relay function on your DCA generator.
Key Features
- Correct Switching Specification — Matches the original relay's coil voltage and contact rating, ensuring the heater circuit activates and de-activates at the correct thresholds.
- Genuine OEM Component — Manufactured to Multiquip's original design intent, not an approximated substitute, so electrical behavior in the heater circuit remains predictable and consistent.
- Direct Plug-In Replacement — Connector configuration and mounting footprint match the original relay position in the DCA generator control panel, allowing straightforward installation.
- Broad DCA Series Compatibility — Confirmed fit across DCA150SSCU4i, DCA220SSCU, DCA220SSCU4I, DCA300SSCU2, and DCA300SSCU4i Super-Silent generator models.
- Cold-Start Circuit Integrity — A correctly functioning heater relay ensures the engine pre-heat system operates on demand, which is critical for cold-weather starts and protecting diesel engine components from cold-crank stress.
The heater relay controls the electrical supply to the engine's block heater or intake air heater circuit, switching power on and off in response to signals from the generator's control system. When this relay fails, the heater circuit may not energize at all, making cold-weather starting unreliable and potentially causing hard-start damage to the diesel engine over time. Replacing a failed heater relay with the correct OEM part restores the circuit's intended behavior and protects engine longevity in low-temperature operating conditions.
