The MVAJ 11 to 34 matches the economical MVAJ051 to MVAJ205 range tripping relays that is aimed to sustain the past users that prefers these models. Featuring high-speed operations and offering low burden alternatives, this range of tripping relays definitely are meant to satisfy the historical users.
There are three groups of MVAJ relays and all are for DC operation only with models that has surge proof countering high capacitance discharge currents in the DC supply system. Conformed with ESI 48-4 Class EB2 are the high burden tripping relays while Low burden tripping observes ESI 48-4 Class EB1. The third grous, control relays, are in line with the National Grid Company SPEC.NGTS 2.19:1996 requirements and are also immune to AC.
