Fire rated switch disconnectors

General characteristics
Stringent requirements according to standards EN 12101-3 have originated a highly demanding research task aiming to reach optimal resistance to high temperature operation.

Enclosure
The enclosure has direct contact with the heating source and acts as a firewall diminishing direct heat into the switch.

Advanced materials
High performance polymers mixed with additives succeed to obtain high temperature switches able to resist erosion while offering stable dimensions under high temperature conditions (controlled CTE) while keeping component lubricity and mechanical performance.
• F300 switch can be identified by its Light brown exterior colour. Employed materials offer excellent characteristics to temperature changes.
• The switch body on the F400 and F600 present a larger size containing specific mechanical elements on materials resistant to high temperatures.
• We recognise F400 switches by its external black colour whereas class F600 switches are identifies by its white colour.

IP65 protection
Sealing injected on the enclosure lid ensuring an IP65 degree of protection according to EN 60529
