Cole Hersee SureStart Compact Low Voltage Disconnect Switch with Harness - 48513-01-BX

Product Condition: NEW

Availability: In stock


SSL Cerficate

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.
