12V Voltage Sensitive Relay

Bought 2 off as Caravan Technology price is cheaper than most other VSR’s that boast 140A current capability. However,the 140A is a little misleading as the operating current is actually 120A continuous but can supposedly handle 140A intermittently (& if you think you may pull 120A from a ‘good’ battery to a deeply discharged battery i would recommend using proper multistrand battery cable of at least 70mm sq (dependant on length of cable run) to avoid volt drops. in the cable at these high currents,which may confuse the voltage-sensing electronics).
