3RA2814
The 3RA2814 solid-state time-delay auxiliary switch has the following features:
●
Voltage is supplied directly through plug-in contact A2 through the contactor's coil
terminals and terminal A3 on the timing relay.
●
The timing function is activated by switching on the contactor on which the solid-state
time-delay auxiliary switch is mounted, via A1 on the contactor coil.
●
The 3RA2814 operates with a control signal.
●
The minimum ON duration at the start contact is 35 ms.
●
A varistor is integrated in the solid-state time-delay auxiliary switch to attenuate contactor
coil switching overvoltages.
