VAL-MS 750/30-ST - Type 2 surge protection plug

Type 2 surge protection plug with a varistor for VAL-MS base element, thermal monitoring, visual fault warning. Design: 750 V AC

  • Quality proven millions of times over in the widest range of applications
  • Rapid installation with bridges, thanks to industry-standard overall width of 1 HP
  • Easy testing and insulation measurement, thanks to pluggable protection modules
  • Can be used in high-performance industrial networks and wind turbine generators (stator) due to the high nominal voltage
Technical Specifications

General

NoteFor use in all low-voltage systems between L-PEN.Only for use in IT systems between L-PE if the bodies of the equipment in the low-voltage system are connected to the grounding system of the transformer station. (common grounding of the HV transformer station and the bodies of the LV consumer's installation. RE = RA according to IEC 60364-4-442/VDE 0100-442 Figure 44D/example a)
