MVAA ( ALSTOM) / ( AREVA)

the MVAA is a low burden relay which can be used where a scheme demands several contact for event recording, alaram initiation, contact login arrangement, etc. the relay can supplied fitted with normal duty contact/ or with heavy duty blow-out contact. MVAA relay are voltage operated armature units of compact design with a positive action and a hight degree of mecanichal stability. voltage is applied to the relay coils via in a internal diode bridge which enables relays to be energised from AC or DC power supplies..
