NJB1-S Time Delay Relay
1. General
NJB1-S Series Monitoring Protection Relay is applicable for
controlling circuit @ A.C. 50Hz/ 60Hz, up to 380V rated
supply voltage and up to D.C.24V supply voltage as
monitoring protection element to make or break circuit
according to preset value.
NJBI-S time-delay relay is used in controlling circuit as time
delay element to make or break circuit according to preset
time.
