Specifications: The coil voltage is not the main contact voltage and the nameplate marks the coil working voltage. For example: the voltage of the coil is 24V, then A1.A2 can not be connected to a voltage other than 24V. And wrong connection will cause the coil to not work or burn the coil. Type 1 is 24V, type 2 36V, type 3 48V, type 4 110V, type 5 220V, type 6 380V.
