o Low power consumption as low as 1mW
o No moving contacts; hence associated problems of arcing, contact bounce, erosion, replacement of contacts
o No gravity effect on operation of static relays. Hence can be used in vessels ie, ships, aircrafts etc.
o A single relay can perform several functions like over current, under voltage, single phasing protection by incorporating respective functional blocks. This is not possible in electromagnetic relays
o Static relay is compact
o Superior operating characteristics and accuracy
o Static relay can think , programmable operation is possible with static relay
o Effect of vibration is nil, hence can be used in earthquake-prone areas
o Simplified testing and servicing. Can convert even non-electrical quantities to electrical in conjunction with transducers.
