Switching Relay

A simple single-pole, single-throw relay for remote switching of components.


For dimensions, see table.

Charger Interlock Relay

A double-pole, double-throw relay to disable during charging, so that it can't be driven away still plugged in. When activated by AC input, this relay breaks the circuit between the ignition key and the potbox microswitch. Comes with 120VAC or 220VAC pull-down coil.


For dimensions, see table.

Terminal Blocks

Terminal blocks are often handy when you have multiple connections feeding to a common power source or ground. We offer two types.

Fuse Block

A fuse block serves the same purpose as a terminal block, with the added feature of fusing each connection.


For dimensions, see table.

Fusible Link

A fusible link should be inserted in the traction battery circuit in each pack in the vehicle. This will blow and break the circuit in case of a short.
