As this is a Unit Verification Certificate, no QAR is applicable as this certificate is specific to the items listed by serial number or other unique identification.
The Range of Z-Series Shunt Zener Diode Safety Barriers is designed to restrict the transfer of energy, from unspecified safe area equipment to intrinsically safe circuits by limitation of voltage and current. The range consists of barriers covering polarised – positive and negative, non-polarised and non-polarised star connected barriers. The barriers incorporate user replaceable fuses.The barriers consists of electronic components on a single printed circuit board encapsulated within moulded plastic enclosure which incorporates two to four terminals with separate earth terminal at both the hazardous and non-hazardous area ends and an integral spring mounting foot, designed for a DIN rail.The barriers are asymmetrical and have light blue hazardous area terminals. Whilst the barriers have user replaceable fuses they also incorporate encapsulated non replaceable fuses for the protection of safety components.See Certificate Annex for series range and electrical parameters
