Topp electric actuator model C40 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 400 N. Quick-release attachment to the window frame. Maximum stroke 500 mm with stroke adjustment in 7 positions (100, 150, 200, 250, 300, 400, 500 mm) by means of a dedicated adjustment knob. Electronic closing limit stop by current sensing. Safety device to reduce the pulling force over the last 10 cm of the stroke. IP55 protection rating for the electrical components. On request, an S version is available, pre-set for synchronisation and simultaneous operation of two actuators installed on a single window.
C40 is a sturdy and reliable chain actuator, with above-standard thrust and stroke, that can be installed on large windows for top-hung, bottom-hung and dome applications in commercial and industrial settings.
CE-marked device.

Frequently Asked Questions
How much force and what maximum stroke does the C40 have?
The C40 delivers 400 N with a maximum stroke of 500 mm, adjustable to 7 positions (100, 150, 200, 250, 300, 400, 500 mm) via a knob.
What safety devices does the C40 integrate?
It integrates the electronic limit stop on closing by current absorption and a safety device that reduces the pulling force in the last 10 cm of the stroke, so as not to overstress the window on closing.
What is the protection rating and can it be synchronised?
The protection rating of the electrical devices is IP55. On request the S version for synchronising several actuators is available. It runs at 230V 50Hz or 24V DC. CE marked.
