Zener Barrier

Raychem TraceTek TT-ZENER-BARRIER is a range of protective safety barriers for use when sensing cables need to be installed in hazardous Class 1 Divison 1 (or Zone 1) areas. The zener barrier is installed between the alarm module and the sensing cable. The safety barrier ensures that, even if the alarm module suffers a multiple failure, the energy transferred to the sensing cable (and thus to the hazardous area) will remain below explosive ignition levels, thus reducing the risk of fire or explosion.
