Type 1 2 / Class I II / Class B C Surge Arresters
PIVM is lightning + surge arrester type 1+2 and class I+II according to EN 61643-11 and IEC 61643-1. Complete device consists of a base part and pluggable module. These arresters are recommended for use in the Lightning Protection Zones Concept at the boundaries of LPZ 0-2 (according to IEC 1312-1 and EN 62305) for equipotential bonding and elimination of transient over voltage that originate during atmospheric discharges or switching processes. The combination of PIVM + B25M is suitable for use in TNS and TT systems.
The modular PIVM surge arresters design set new standards in terms of safety and user friendliness. The proven protective circuit with heavy-duty zinc oxide varistors in combination with the “Thermal Disconnecting Control†monitoring device are characteristic of the PIVM series type 1+2/class I+II arrester.
The pluggable modules ensures the proper & strong fixing to the base part. Neither vibration during transport nor the enormous electromagnetic forces of discharge can loosen the modules. For the replacement purpose, they can be easily replaced without tools by simply pulling out the protection modules.
The “Thermal Disconnecting Control†monitoring device in the varistor based surge protection devices are well proven technology in terms of safety and considers practical applications where arresters might be damaged. Hakel surge arresters with “Thermal Disconnecting Control†mechanism, the intensity of the discharge current and the surface temperature of the heavy-duty varistor are evaluated.
The visual indication of green and red indicator flags shows the proper functioning of every protective circuit and varistor. Apart from this standard visual indication, PIVM... DS devices feature a three-pole remote signaling terminals (Potential Free Contact). With its floating changeover contact, the remote signal can be used as a make or break contact depending upon the circuit concept.
