VAA21/22/23 are double pole versions of VAA 11/12/13 respectively. VAA relays are voltage operated relays. The relays are attracted armature units of compact design with positive action and a high degree of mechanical stability. The relays can be supplied with self, or hand reset contacts and changeover contacts. When it is necessary to break heavy or highly inductive dc loads, heavy duty magnetic blow out type contacts can be provided. These contacts use the
magnetic field of a small permanent magnet to force the arc onto the arcing horns away from the contact tips. Auxiliary relays with delay on pick-up or drop-off can be supplied on specific request. Similarly relays with magnetic
blow out contacts can also be supplied on specific request. The standard VAA relays provide only instantaneous self or hand reset contacts. To ensure a longer operating life, the tips of the silver contacts have a domed profile, the optimum design for the repetitive operation duties of industrial applications. Although the standard designs are suitable for dc and full-wave rectified ac systems only, alternative versions for ac operation are available.
