48513-01 SureStart Compact Low Voltage Disconnect Switch, & Harness

LVD & Harness (Deutsch-type connector and wires).

No more dead batteries!
12 or 24V, 125A at 60ºC, 100A at 85ºC

Electronically senses battery voltage and conserves starting power. Automatically disconnects and reconnects loads based on battery condition; no operator action is required to protect the batteries.
Prolongs battery life by preventing damage due to excessive discharge. Eliminates the need for both separate timer or voltage sensing delay relay devices and high current relay or solenoid, and simplifies wiring and installation.
Small size and lightweight design means easier and more discrete mounting, to use space more efficiently, eliminate hardware, and give better routing of wires.

When battery voltage falls below programmed voltage setting for 2 minutes non-critical loads are automatically disconnected.
Waterproof and dustproof to IP67 international standard. (Submersible to 3 feet.) Sealed connector makes it ideal for harsh environments.
Advanced technology enables a robust product in a small lightweight package. Programmable timer feature automatically disconnects loads after key off, regardless of battery condition.
12804 Harness fits this LVD.
Humidity: 0 to 90 %RH.
Vibration: 10-500 Hz per SAE J1455.
Shock and Thermal Shock: per SAE J1455.
Inductive Transient: +/- 600V per SAE J1455.
Load Dump: + 100V per SAE J1455. Battery Terminal Torque: 50 in-lbs max.
Operating Voltage: 9V min, 12V typical, 16V max if used with 12V DC systems.
