English Electromotive actuator for air dampers and control valves on low to medium output oil and gas burners. SQN70.664B20 is the replacement for SQN30.401A2700, SQN70.664A20
If used as a replacement for SQN3... AGA70.3 mounting kit must be used. (Not included in the scope of delivery).
Application:
The actuators SQN7... are designed for actuating gas and air dampers on oil and gas burners with low and medium heat output, for load-dependent control of the fuel and combustion air volume:
- in conjunction with P-PI or PID controllers, e.g. RWF40...
- directly via the various automatic burner controls, e.g. LFL..., LME..., LMG..., LMO..., LOA...
- in conjunction with single-wire, 2-wire or 3-point controllers
Technical data:
Type: SQN70.664A20
Mains voltage: AC 230 V -15%/+10%
Mains frequency: 50...60 Hz ±6%
Motor of the actuator: Synchronous motor
Power consumption: 6 VA
Control angle: Max. 160°, scale range 0...130°
Installation position: Any
Protection class: IP40 to DIN 40050, with appropriate design of the cable entries and screw fixings
Protection class: II according to DIN EN 60730
Cable entry: Plug-in gland holder with thread for 2 x Pg9, no locknut required
Other Siemens SQN actuators are also available on request!
