Switching actuator,
2-channels SA3-02B

EAN: 8595188132367 | Code: 3236 standard


  • Actuators are designed for switching of one (SA3-01B), respectively two (SA3-02B) of various appliances and loads by relay outputs (potentialless contacts).
  • SA3-01B contains 1 relay with switching potentialless contact with max. load 16 A/4000 VA/AC1.
  • SA3-02B contains 2 relays with switching potentialless contacts with max. load 8 A/2000 VA/AC1.
  • Output contacts are separately controllable and addressable.
  • Thanks to changeover contacts, the SA3-02B actuator can be used to control a 230 V drive (such as blinds, shutters or awnings), whereas by proper bridging of contacts, it is possible to secure locking hardware options while switching on phase two outputs.
  • Actuators are equipped with a temperature input for connecting an external two-wire temperature sensor TC/TZ (see accessories).
  • LED on the front panel signalizes the state of each output.
  • SA3 is normally supplied in the option AgSnO2 contact material.
  • SA3-01B, SA3-02B are designed for mounting into the installation box.


  • Number of contacts: 2x CO, 8 A
  • Switching current: 8 A / AC1
  • Switching output: 2000 VA
  • Supply voltage (frequency): BUS 27 V DC
  • Rated current from BUS: 50 mA (at 27 V DC)
  • Housing: BOX
  • Dimensions: 49 x 49 x 21 mm
