JCB Electrical Relay 14V 5-pin 35A/20A
Relay designed for the electrical systems of JCB machines. This component acts as a remotely controlled switch, enabling safe control of high-current circuits (e.g., lighting, fans, fuel pumps). The 5-pin configuration allows it to operate in normally open or normally closed modes, making it a key element of control modules in a wide range of construction and agricultural machinery.
Specifications and Technical Parameters:
- Rated Voltage: 14V DC (standard for 12V systems).
- Number of Pins: 5 (changeover configuration).
- Load Capacity: 35A (normally open - NO) / 20A (normally closed - NC).
- Housing: Durable plastic resistant to vibrations and high temperatures found in engine compartments.

Technical Advice: If one of the systems (e.g., work lights or heating) stops working and the fuse is intact, the relay is often the culprit. A "click" when switching on doesn't always mean the relay is functional – internal contacts can become burnt and fail to conduct current. When replacing, check the fuse box socket for signs of overheating (melted plastic). Always use relays with specifications matching the original – lower amperage ratings will lead to rapid component failure.
