Technical specifications
Application
Toxfree® ZH RZ1C4Z1-K (AS+) is a fire resistant cable, specially designed to ensure the power supply to emergency circuits in the event of fire. During a fire you need critical circuits to work for life safety (signalling lights, fume extractors, acoustic alarms, water pumps, etc) and a secure plant shutdown. For this reason, its use is highly recommended in public places such as hospitals, tunnels, offices, production plants, laboratories, hotels, etc.
