Cartek Battery Isolator XR Unit Only With Connection Cable

The XR Battery Isolator is the latest generation of motorsport master-switch devices from CARTEK. At 30% smaller size and 40% lighter weight than the previous ‘standard’ and GT isolators, this XR version offers even more benefits and performance when compared with traditional mechanical master-switches and electro/mechanical safety cut-outs.

  • External operation by single or multiple 'strike' button(s)
