Dongfeng Kinland Wiping intermittent relay assembly 3735020-C0100

Exclusively designed for Dongfeng Kinland heavy-duty trucks, this relay assembly adheres to strict OEM dimensional and electrical specifications, ensuring seamless integration with the vehicle’s existing wiper system and electrical harness. Its physical housing matches the factory mounting slot in the truck’s dashboard or fuse box, and its electrical connector (typically a 4-pin or 6-pin configuration) aligns perfectly with Dongfeng Kinland’s wiring pinout—enabling plug-and-play installation without wire splicing or adapter use. The relay’s voltage rating (12V or 24V, matching Dongfeng Kinland’s electrical system) and current output (optimized for the truck’s wiper motor power) guarantee compatibility, avoiding issues such as motor burnout or relay failure that can occur with generic aftermarket parts

Built with high-quality electronic components (including surface-mount resistors, capacitors, and a durable electromagnetic coil), the 3735020-C0100 relay assembly delivers stable electrical performance even in harsh operating conditions. It features built-in overload protection: if the wiper motor draws excessive current (e.g., due to blade jamming from ice or debris), the relay automatically cuts power to prevent damage to the motor or wiring. Additionally, the relay’s circuit board is coated with a conformal layer (typically acrylic or silicone) that resists moisture, dust, and corrosion—critical for maintaining functionality in the damp, dusty environment of a truck’s engine bay or fuse box. The electromagnetic coil is rated for long-term use (over 100,000 activation cycles), ensuring reliable signal transmission to the wiper motor

The relay assembly’s outer housing is constructed from heavy-duty ABS plastic (acrylonitrile butadiene styrene) with a impact-resistant design, capable of withstanding minor shocks and vibrations common in heavy-duty truck operations (e.g., rough road surfaces or engine vibration). It achieves an IP54 ingress protection rating—meaning it is dust-resistant and protected against splashing water from any direction—making it suitable for use in rainy, snowy, or dusty environments. The housing also features heat-dissipating ribs that prevent overheating, even when the relay is activated continuously (e.g., during heavy rain). This durable construction ensures the relay maintains performance in extreme temperatures, ranging from -40°C (cold winter conditions) to 85°C (hot engine bay environments)

The Dongfeng Kinland Wiping Intermittent Relay Assembly 3735020-C0100 meets rigorous global safety and electrical standards, including ISO 16750 (environmental conditions for electrical and electronic equipment in road vehicles) and ECE R10 (automotive electromagnetic compatibility). It undergoes comprehensive testing to validate its reliability: electrical performance tests (voltage fluctuation resistance, current stability), environmental tests (temperature cycling, humidity resistance, salt spray exposure), and durability tests (vibration endurance, cycle life). The relay also complies with automotive EMC (electromagnetic compatibility) requirements, ensuring it does not interfere with other electronic systems in the truck (e.g., GPS, radio, or engine control unit) and is not affected by external electromagnetic interference. By meeting these standards, the relay ensures safe, reliable wiper operation— a critical component of driver safety and vehicle roadworthiness
