The MVAA is a low burden auxiliary relay. It is a compact relay which is utilized to provide several contact requirements for protection schemes. These multiple contact requirements can be provided by using a wide voltage range. The MVAA is user-friendly and is mechanically stable.
There are three reset versions which are suitable for a wide voltage range. These are manual, self and electrical reset versions. The high mechanical stability enhances the positive action and the compact design of the MVAA.
