• Continuous Current Rating 125A

• Intermittent Current Rating 140A

• Power Consumption 10mA ( Standby )

• 330mA ( Engage ) 0mA ( Storage Mode )

HULK 4x4 Dual Battery Isolators / Voltage Sensitive Relays have been specifically designed for a wide range of 12V applications.

HULK 4x4 Dual Battery sense the input voltage generated and automatically content / disconnect the appliance or circuit at pre-set voltages, eliminating the possibility of discharging the primary starting battery. Constructed with a weatherproof body (IP65) and durable silver tipped contacts, Dual Battery Isolators also feature surge protection and a L.E.D indicator designed to alert the user when the unit is engaged.
