How a MAXIMUM VOLTAGE RELAY (RHV) works:
Supposing it is to control a load with the following ratings:
I
= 5 A
n
V
= 230 V ac (rated regular operating voltage)
n
V
= 250 V ac (voltage at which RHV relay is requested to trip)
max
1°
Connect as shown in diagram (for V
N.B.: Normally, connect terminals:
7-10 if V
7-11 if V
7-12 if V
