12V/24V 40A–60A Automotive Relay

Product Overview

FUZTRAX provides professional automotive relay solutions for vehicle electrical systems, wiring harnesses, fuse relay boxes, aftermarket accessories, and OEM electrical projects.

Our standard automotive relays are available in 12V and 24V configurations with a 40A contact rating, while higher-current versions can be customized up to approximately 60A within the same compact housing size, depending on contact material, terminal design, coil specification, and project requirements.

Both 4-pin and 5-pin configurations are available, supporting normally open and changeover switching functions for a wide range of automotive and DC electrical applications.

In addition to standard relay models, FUZTRAX can provide customized solutions according to customer requirements for materials, dimensions, electrical specifications, contact configuration, housing, terminals, marking, packaging, and certification.

Our goal is to provide reliable automotive relays with stable electrical performance, consistent production quality, and flexible OEM manufacturing support.

Suitable for applications requiring switching between two circuits or normally open / normally closed control.

Relay terminal layouts can be configured according to customer project requirements.

Normally Open & Changeover Relay Options

Available switching configurations include:

Normally Open (NO)
Suitable for conventional accessory switching where the output circuit is activated when the relay coil is energized.

Changeover (SPDT)
Suitable for applications requiring both normally open and normally closed outputs.

Different internal contact arrangements can be selected according to the required control logic.
