"MB4" PASSIVE SAFETY ZENER BARRIERS, FOR ATEX ENVIRONMENTS

  "MB4" PASSIVE SAFETY ZENER BARRIERS, FOR ATEX ENVIRONMENTS
 

MBA: kit of zener barriers for hazardous areas.

KIT of three intrinsic protection zener barriers, for connection of devices en ATEX area with devices in safe area. Suitable for mounting on a panel board on an omega bar in a safe area, or in a hazardous-proof case, for intrinsic safety weighing systems in hazardous area. Marking of single barrier: Ex II (1) GD [Ex ia] IIC [Ex iaD].
