Multi-Model Compatibility:Directly replaces 372 4D0 951 253 and cross-compatible with 40A 12VDC relays matching ISO 280 mini housing (e.g., 0 332 209 126, 4RD 933 791-04)
High-Load Durability:Silver-tin oxide (AgSnO₂) contacts handle 40A continuous current (resistive) and 25A inductive loads (e.g., fuel pumps), preventing overheating and contact welding
Plug-and-Play Installation:Standard 5-pin SPDT layout (pins 30-85-86-87-87a) matches OEM sockets; no wiring modifications required
Critical Fault Resolution:Fixes common failures like ignition cutoff (code P0351) or fuel pump no-start (P0087) caused by worn relays
Certified Reliability:RoHS-compliant with IP52 dust/moisture resistance (-40°F to 185°F operational range)

وصف

Universal Automotive Relay for High-Demand Systems
This 40A 12VDC SPDT relay is engineered to replace OEM part 372 4D0 951 253 and compatible models, delivering OEM-grade performance in critical vehicle systems.

Key Specifications

Compatibility: Interchangeable with Bosch 0 332 209 126, HELLA 4RD 933 791-04 (verify pin layout).

Rated Load: 40A @ 12VDC (resistive) / 25A @ 14VDC (inductive).

Environmental: IP52 housing withstands engine bay vibrations and humidity.

Typical Applications

Fuel Delivery: Restores stable voltage to electric fuel pumps in gasoline engines.

Ignition Circuits: Resolves intermittent starting failures in ignition modules.

Auxiliary Lighting: Supports HID/LED headlight stability without flickering.

Installation Guide

Confirm original relay part number and pin configuration (5-pin SPDT).

Align housing arrow with socket orientation to prevent reverse installation.

Test system functionality before finalizing installation.
