Battery Disconnect Switch 300A 12V/24V – Winch Isolator

This battery isolator switch, also called a battery master switch, kill switch or cut-off switch, fully disconnects the battery from the vehicle's electrical equipment. It's rated for 300 A continuous and 2000 A peak current, which makes it suitable for high-power winches that draw several hundred amps at full load. It also fits 4x4s, pickups, trucks, trailers, motorhomes, boats and machinery.

Winch installation: fit the battery disconnect switch on the positive (+) cable between the battery and the winch. Power the winch only while you're using it, and remove the key to cut the power when you're done. This protects both the winch and the vehicle.

Benefits:

• Protects the electrical circuit in case of a short circuit
• Prevents the winch from being switched on by accident
• Allows safe maintenance and repair work
• Reduces battery discharge during long periods of non-use
• The removable T-key also works as a simple anti-theft measure
• Metal face plate and copper contacts for durability and reliability
