The HEA multicontact auxiliary relays represent high speed devices capable of performing a multitude of parallel operations.
The HAA Auxiliary or Annunciator Relays are available in two versions one operated by current and the other by voltage in addition to two general case designs. Examples of these units include the 0.2/2 A DC operated HAA15A4 and a 125 VDC operated HAA15B5. The HAA 15 is a representative of single units that are provided in a molded plastic case with glass window, while all other versions come in a standard drawout case.
