Topp electric actuator model C20 with double-link articulated chain, housed in a dedicated casing, complete with bracket and accessories for top-hung outward or bottom-hung (tilt) opening. Operation at 230 V 50 Hz or, alternatively, at 24 V DC. Maximum applicable load 300 N. Quick-release attachment to the window frame. Stroke adjustable from the outside via a selector switch with stops at 240 and 360 mm (for C20 tandem, fixed 360 mm stroke; special stroke available on request when ordering). Force adjustable from the outside via a selector switch. Electronic closing limit stop by current sensing.
C20 is a sturdy and reliable chain actuator that combines minimal footprint, aesthetic elegance and application versatility in a compact automation. It is particularly suited to installation on roof windows in residential buildings and on top-hung and bottom-hung windows in commercial settings.
CE-marked device.

Frequently Asked Questions
Does the C20 chain withstand peak loads well?
Yes: the C20 uses a double-link chain with extremely high resistance to peak loads.
Is the C20 suitable for applications with minimal footprint?
Yes: it combines a long stroke with compact actuator dimensions, thanks to an internationally patented chain path, for applications requiring minimal footprint.
How does the C20 handle closing?
No: the closing limit stop works by current sensing, avoiding closing adjustments and compensating for any actuator positioning errors.
