2.10 Relay
2.10.1 Physical features
 Single core magnetic latching relay
 Imax = 100A
 Operation life is a minimum of 5,000 times under rated current
 Operation life is a minimum of 10,000 times under no load condition.
 Pulse driven: In order to make sure that the relay can work properly, the voltage exerted
on the coil must reach rated voltage and the width of the pulse must be 3 times longer
than the operation time.
 Short time over current: 30Imax
 In order to operate the relay properly and not to cause a nuisance reset of the meter, the
meter only operates the relay when the supply voltage is higher than 70%Un.
