Battery Disc. Switch 300amp for Alternator

The ALLSTAR PERFORMANCE Battery Disconnect Switch 300amp for Alternator (ALL 80155) is a rotary panel-mount electrical safety device designed for high-amperage battery isolation in 12-volt systems. This switch is essential for vehicles undergoing maintenance, storage, or emergency situations where immediate electrical isolation is required.

With a 300-amp rating, this switch provides manual control over battery power, allowing users to cut power quickly when needed. The alternator-specific post configuration ensures reliable conductivity during high-current charging cycles, while the rotary mechanism facilitates positive switching action.
