Series 31000 - VEC

31000 VEC

Single Vehicle Electrical Center (VEC)

The Eaton Single Vehicle Electrical Center (VEC) is a widely used transportation industry power distribution module. The VEC uses patented programmable 3D matrix technologies that can be easily modified to accommodate changes to an electrical system. The VEC can be customized for each specific electrical system, but require no tooling for implementation.

The VEC accepts automotive components including fuses, relays, circuit breakers, diodes, and other devices that have 2.8mm wide terminals on 8.1mm centerline spacing. The compact size of the VEC (about 4”x4”) provide for high component density. VECs provide either 8.0mm bladed inputs or M8/M6 stud inputs. The VEC can accommodate up to 2 input connectors - 4 bladed inputs or 2 studs - and 4 output connectors with up to 8 outputs each (32 total).


The VEC is ideal for distributed main power as well as auxiliary “add-on” applications. Current VEC applications include Class 3-8 trucks, buses, chassis and RV, Con-Ag equipment, marine specialty vehicles, and automotive power distribution systems.

The customizable designs of the VEC/DVEC enable them to incorporate many different devices and multiple design variations. Splices in the harness can also be eliminated by internally programming them into the grid matrix. The inputs (connector or stud) and outputs (connector) of the VEC/DVEC are color-coded and keyed, and provide quick installation. This makes the module easy to service. The largest benefit of these modules are the reduced lead times and zero tooling cost.
