Description

Description

Standards

  • Test
    IEC 60332-1

Application

Nexans Y(st)Y Dca red is a screened fire alarm cable according to fire classification Dca-s2,d2,a3 for usage in housing, residential and similar installations with a medium fire hazard level. Y(st)Y Dca red is designed for fire alarm, measurement, regulation and control applications in low voltage installation. The metallised foil protects against interference with external electrical fields.
