Minimum voltage protective circuits with time delay operated by
a,c.
Fig.2. The advantage of these circuits is that the
relay EN-500 works entirely without vibration. The way
in which the circuit of Fig.2 may be used to supply the
operating circuit of a circuit breaker is shown in Fis.3.
Figs. 4, 5 and 6 show different methods of obtaining
time delay. Fig. 4 shows a circuit employing relay type
EV-100 which operaVes when voltage is removed from the
winding. The circuit of Fig-5 uses time-relay type MKU-48
