FFX400 1SZ1-R(PH60)(CU/SR/LSZH 600/1000V Class 2)

FFX400 1SZ1-F(PH60)(CU/SR/LSZH 600/1000V Class 5)

Application

The cables are designed for power supply and signals trasmission, indoor or outdoor even wet environment.

They are designed for fixed laying in free air, in pipe or conduit, on masonry and metal structures or suspended

in places where in case of fire people are exposed to serious risks for emission of smoke, toxic and corrosive

gases and where you want to avoid damage to facilities, equipment, goods. They are primarily intended for

feeding of: emergency exits, alarm signals, warning of smoke or gas, escalators.

Standards

Basic design adapted from BS 7629-1
