Auxiliary relays type arevaalstom vaa auxiliary relays are voltage operated relays. It is user. Vaa212223 are double pole versions of vaa 111213 respectively vaa 3133 are triple pole versions of vaa 111213 respectively.
To avoid electric shock or energy hazards after completely isolating the supplies to the relay both poles of any dc supply the capacitors should be safely discharged via the external terminals prior to decommissioning. The mvaa is a low burden auxiliary relay which is used to provide multiple contact requirements for protection schemesthe mvaa auxiliary relay is compact in design is mechanically stable. Manufacturing for mvaa12 mvaa15 and mvaa22 models has been discontinued. The former offers easy accommodation and wiring into the fixed electrical scheme with the relay plugging in as required. Prima has mechanical coding to ensure plug in to the correct socket with a secure snap lock fitting for retention. Should an issue ever arise changing out a relay for a strategic spare is fast and simple.
