Fire rated enclosed switch-disconnectors

The answer to your fire safety needs

Public safety is a priority for ABB. With the new fire rated enclosed switch-disconnectors from 20 to 720 A, we provide a solution to meet all the thermal requirements to keep public areas smoke-free, facilitating a safe evacuation in case of fire.

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
 - 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 OFF or ON/OFF positions.
The enclosures of switches above 125 A are equipped with a security latch that prevents the door from opening in case of short circuit.
