REC Pre-charge Resistor and Relay 11 - 68V

Pre-charge unit is a device that charges the input capacitors of the system components before the main contactor switches on. Pre-charge device eliminates high inrush currents at the switch-on of the contactor and prolongs the contactor lifespan dramatically.
