The MVAX 11 relay type is continually supervising trip circuit of tripping relays and assures that it surely doesn't have any false alarms while protection operations. It has a built-in alarm indicator and manages close circuits. It is made and created vigorously and simply and comes with an armature unit which contains positive actions and encompasses no chatter. It is built with R1 an R2, dropping resistors which are linked with the coil. If ever that circuit being managed opens or if a failure in supply occurs, the relay will be de-energized and will trigger the alarm and the visual signals.
