This isolator is rated at 30 amps, making it suitable for managing medium-current electrical loads commonly found in automotive applications.

It acts as a switch that can break or restore the flow of current, playing a crucial role in the vehicle’s electrical system management and security.
When considering this part, compare it directly with your old isolator in terms of amperage rating, terminal layout, and general condition. The correct match ensures compatibility and reliable operation. This unit is sold as a new part under SKU BB-403687, listed specifically as a Crabtree Classic Isolator, which helps identify and distinguish it from other isolators or switch types.
