FAQ

Questions engineers ask first

What is the difference between FE180 and E30/E90 on NHXH cables?

FE180 (per IEC 60331-21 / VDE 0472-814) tests the cable alone over a 750 °C burner for 180 minutes without circuit failure. E30 and E90 (per DIN 4102-12) certify the complete installed cable-and-support system inside a fire furnace following the standard time-temperature curve up to 1000 °C for 30 or 90 minutes.

When should NHXH E30 be selected versus NHXH E90?

Per German building regulations (MLAR), E30 is specified for emergency escape lighting, fire alarm interfaces and passenger evacuation systems that operate during the initial 30-minute evacuation phase. E90 is mandatory for firefighting elevators, stairwell pressurisation fans, smoke-extraction motors and fire water booster pumps.

When is NHXCH preferred over unscreened NHXH?

NHXCH incorporates a concentric copper wire and counter-helix tape conductor around the core assembly. Select NHXCH when fire-safety power feeders require mechanical cut-through protection, touch-safe earthed screening, or reduced electromagnetic interference alongside control circuits.

Does NHXH require special cable trays to maintain its E30 or E90 rating?

Yes. Because DIN 4102-12 is a system certification, NHXH must be installed using tested and approved fire-rated support brackets, single clamps, or cable ladders at the clip spacing specified in the support manufacturer's ABP test certificate.
