Description

Types

The plug-in module / base design facilitate replacement of a failed module without the need to remove system wiring etc.

  • ISPRO D consists of a high performance varistor block with thermal disconnection device.
  • ISPRO DM consists of two performance varistor blocks with thermal disconnection devices configured to provide multi-pole protection to L-PE and N-PE in one enclosure.
  • ISPRO DMG consists of two performance varistor blocks with thermal disconnection devices and galvanic isolation N to PE for TT single phase networks.

Technical data
