Eaton Electrical
AR-ARD Series Convertible Contact Industrial Control Relays

Key Features

Permanent Magnet Latch

By energizing the relay coil, the latch attachment “sets” (when the base relay’s armature/crossbar assembly has closed) holding the relay ON, even after the relay coil has been de-energized. The clearing coil on the latch is energized to release the armature/crossbar assembly.

  • Field mountable to fourand six-pole
  • Latch plunger is adjustable
  • Latch coil continuously rated
  • Unlatching power requirements
  • Open gap: 24 VA
  • Closed gap: 7 VA
  • Burden: 4 watts AC, 6 watts DC

Surge Suppressor

  • Mounts in contact cavity of AR relays
  • Limits high transient voltages resulting from deenergizing relay coil or other electromechanical devices
  • Protects sensitive instruments and solid-state devices
  • 120 Vac maximum, not used on Vdc
  • For noise suppression, see Catalog Number SS-56 starter mounted surge suppressor.

The AR/ARD relays are electromechanical convertible contact relays. AR relays are AC devices and the ARD is for DC applications. 

Application Description

Type AR and ARD relays are designed for use on machine tools, process lines, conveyors and similar automatic and semiautomatic equipment.


AR relays are available in either four- or six-pole configurations. AR relays are easily converted to eight- or 10-poles simply by adding a four-pole deck. In addition, mechanical latch attachments are available with four- and six-pole relays. 

Contacts are convertible from NO to NC, to provide any combination desired up to a maximum of 10. For the ARD, the number of poles cannot exceed four NC in any pole configuration. Wide spacing of contacts simplifies installation, contact testing and maintenance. Contacts are electrically and mechanically isolated from each other. Overlap contacts are also available in one or two sets. These contacts should be mounted in the center pole positions. AC and DC contact cartridges should not be used in the same relay.
