Reliable in extreme conditions
The enclosure material has been specially designed for installations where the power supply must be maintained even at high temperatures. To ensure a safe and reliable operation in abnormally hot environments, our switches have been tested according to the standard EN 12101-3. 
The enclosed switch-disconnectors have been designed to maintain the power supply at the temperatures and for the periods of time below:
 - F200: 200⁰C in 120 min
 - F300: 300⁰C in 60 min (tested for 120min) 
 - F400: 400⁰C in 120 min

Safety and Protection
Our rated enclosed switch-disconnectors maintain the power and provide isolation to essential smoke extraction and ventilation equipment. Padlocking is possible in ON and OFF positions.
