Standard contacts are of silver/copper alloy. They are shaped and positioned to ensure a reliable and low resistance
normally open or normally closed contact. Standard VAA 13 relays are suitable for dc supply only. VAA21/22/23 are double pole versions of VAA 11/12/13 respectively. VAA 31/33 are Triple pole versions of VAA 11/12/13 respectively.
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.
