Alstom VAA33ZG8314FCH 220V DC General description

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.

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 11/21 relays are suitable for ac/dc supply and standard VAA 13/23 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. The breaking capacity of the heavy duty contact is shown by the curves in Figure 1.

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 pro- file, 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.
