Hella Relay Plug In DIN Rail Mount Metal Contact Relay Model H84988001

Description

Product Overview

The Hella Relay is engineered as a plug in, DIN rail mountable component designed for reliable performance in automotive electrical applications. Constructed with robust metal contacts, the relay handles a continuous current of 0.1 A while maintaining low contact resistance. Its compact dimensions of 5.7 × 4.9 × 3.8 inches and a weight of 7 ounces allow easy integration into tight panel spaces. The device complies with SAE J2544 and IEC EN 60947 standards, ensuring it meets industry safety and durability requirements. Hella’s reputation for quality is reflected in the painted exterior finish and the precise engineering of the plug in connector, which simplifies installation and replacement.

The relay’s normally open contact configuration provides a clean break in the circuit until the coil is energized, reducing the risk of unintended power flow. The manual operation mode gives technicians direct control during diagnostics, making it a practical choice for service bays and field repairs. The part number H84988001, also listed as the OEM and manufacturer part number, guarantees compatibility with a wide range of vehicle models that reference this specification. The product is packaged conveniently for quick deployment, and each unit carries a one year limited warranty that covers material defects.

Installation on a DIN rail follows standard mounting procedures: the relay slides onto the rail and locks into place without the need for additional hardware. The plug in connector aligns with the corresponding socket, delivering a secure electrical link that resists vibration and thermal cycling typical of automotive environments. The metal contacts are coated to prevent corrosion, extending service life even in harsh climates. The relay’s design also supports easy visual inspection; the painted housing highlights the orientation and status of the contacts, aiding rapid verification during routine maintenance.

From a performance perspective, the Hella Relay offers consistent switching characteristics across its rated temperature range, delivering predictable response times that are essential for timing critical systems such as fuel pumps, lighting circuits, and sensor interfaces. The device’s low power consumption during idle periods contributes to overall vehicle efficiency. By adhering to recognized standards, the relay integrates seamlessly with existing wiring harnesses, reducing the need for custom modifications. The inclusion of the UPC 760687629436 facilitates inventory tracking and simplifies ordering for distributors and repair shops.

Usage

The relay is ideally suited for automotive performance electrical system upgrades, where reliable switching and durability are paramount. It can be employed in applications ranging from auxiliary lighting control to engine management modules, providing a dependable interface between control units and power circuits. Its plug in format allows quick swaps during testing, enabling engineers to evaluate circuit behavior without extensive rewiring. The DIN rail mounting makes it a natural fit for aftermarket control panels and custom builds that require organized, space efficient component layouts.

In service environments, technicians benefit from the manual operation mode, which permits direct activation of the relay for troubleshooting purposes. By applying voltage to the coil, the operator can verify that downstream devices receive power as expected, isolating faults in complex wiring diagrams. The robust construction tolerates the vibration and temperature fluctuations encountered in both on road and off road conditions, ensuring consistent operation over the vehicle’s lifespan. The relay’s compliance with SAE J2544 and IEC EN 60947 also means it meets the regulatory expectations of professional repair facilities.

Installation follows a straightforward three step process: first, secure the relay onto the DIN rail using the built in mounting clips; second, align the plug in connector with the corresponding socket and press until a firm click is felt; third, verify polarity and test coil voltage to confirm proper engagement. The clear labeling on the housing indicates the coil and contact terminals, reducing the chance of wiring errors. Because the relay does not require soldering, the procedure can be completed in minutes, even in confined engine bays.

FAQ

What current rating does the Hella Relay support?

The relay is rated for a continuous current of 0.1 ampere. This rating is suitable for low power control circuits commonly found in automotive lighting, sensor, and auxiliary systems. The rating ensures that the contacts can handle the expected load without excessive heating, while still providing reliable switching performance.

Can the relay operate reliably in high vibration environments?

Yes. The relay’s construction includes a rugged metal contact set and a painted housing that together resist the mechanical stresses typical of automotive applications. It has been tested for vibration and shock according to SAE J2544, confirming that the electrical connection remains stable even when subjected to road and off‑road conditions.

How does the plug in mounting benefit installation compared to traditional screw type relays?

The plug in format eliminates the need for tools or soldering during installation. Technicians simply slide the relay onto the DIN rail and press the connector into the matching socket, achieving a secure electrical link in seconds. This reduces installation time, lowers the risk of wiring errors, and makes replacement or upgrades straightforward, especially in confined engine compartments.

What warranty coverage is provided with this relay?

Hella offers a one year limited warranty that covers defects in materials and workmanship. The warranty does not extend to damage caused by improper installation, misuse, or external factors such as accidents. Customers can contact Hella’s support team with the part number H84988001 to initiate a warranty claim if the product fails within the warranty period.
