Fire Rated Wiring System
Protect Critical Circuits In Case Of Fire
- Worldwide regulations require fire protection for emergency feeder circuits in commercial buildings, public spaces, hospitals, industrial plants and refineries. Critical equipment and processes must continue to operate during an emergency to minimize damage and protect lives.
- Setting the Standard in Fire Safety.
- Historically, fire safety of critical circuits was achieved by running conventional cables behind a heat barrier such as a gypsum board or hollow concrete block; or by embedding the conductors in concrete. nVent PYROTENAX mineral insulated fire-rated cables are UL listed and can withstand temperatures up to 1850°F (1010°C) for two hours. This built-in fire resistance provides greater protection as opposed to the fire-rating of conventional cables which require heat barrier systems.
