48510 SureStart Low Voltage Disconnect Switch, 200A

No more dead batteries!

200A at 12V DC

Ensures ample starting capacity and prolongs battery life. Automatically disconnects non-critical loads from a battery when the battery voltage falls below a predefined threshold. Automatically reconnects the loads to the battery when it is being charged.

Manual override permits a user to make or break the connection, regardless of battery voltage.
Overcurrent, short circuit and over-temperature protection.

No more stranded vehicles! Avoid the time and expense of getting your vehicles towed. The SureStart LVD ensures there’s enough power to start, and saves the batteries on vehicles that aren’t used every day.
