If the 3RA2812/3RA2832 electronic timing relay with semiconductor output is fitted, the
contactor coil is contacted through the timing relay.
Note
Contactor coil terminals A1 and A2 must not be connected.
3RA2813
The 3RA2813 solid-state time-delay auxiliary switch has the following features:
●
The voltage is supplied through the plug-in contacts directly via the contactor's coil
terminals, parallel to A1/A2.
●
The timing function is activated by switching on the contactor on which the solid-state
time-delay auxiliary switch is mounted.
●
A varistor is integrated in the solid-state time-delay auxiliary switch to attenuate contactor
coil switching overvoltages.
