Switching actuator, 2-channel SA3-02M


EAN: 8595188132374 | Code: 3237 standard


  • SA3-02M is a switching actuator containing 2 independent relays with changeover potentialless contacts. 
  • Maximum load per contact is 16 A/4000 VA/AC1.
  • Each of the two output contacts are individually controllable and addressable.
  • Both relays are individually decorated input terminals, and therefore can switch various independent potentials.
  • The actuator is designed for switching up to two various appliances and loads relay output (potentialless contact). 
  • Thanks to changeover contacts, it can be used to control one 230 V power (such as blinds, shutters or awnings) with appropriate bridging, the contacts can secure hardware blocking the possibility of simultaneous switching of the phase on both outputs, see example of connection.
  • LEDs on the front panel signal the status of each output.
  • Contact status of each relay can be changed separately and manually by control buttons on the front panel.
  • Switching actuators SA3 are normally supplied in the option AgSnO2 contact material.
  • SA3-02M in 1-MODULE version is designed for mounting into a switchboard, on DIN rail EN60715.
