dear all, in motor operation , motor is of 100 hp and
bimetal relay setting is 130 amp, if relay is getting
tripped on 120 amp balance current what can be the
reason? Relay is newly replaced. I dont know but is
there any frequency effect in thit case? Can frequency
variation affect bimetal relay operation?

Bimetallic relays are not very accurate.Ambient temp also
plays a role for setting as the relay acts at a certain
temp.Hence you have to compensate for ambient
temp.Frequency has no effect on the setting .
