Product description

The fuse monitors IL/IP/SL/SP 9075 of the VARIMETER series monitor up to 3 load fuses. Early detection of blown fuses, even when loads are switched off, and preventive maintenance prevent costly damage and, as a user, you benefit from the operational reliability and high availability of your system.

Technical specifications

Enclosure design: Switch cabinet
Type: SL 9075


  • Increased system availability through early detection of fuse failures, which can cause considerable damage to systems
  • Rapid detection of fuse failures, even when consumers are switched off, ensures system availability at the earliest possible point in time
  • Reliable detection of fuse failure, even with an unbalanced or harmonic network and with regenerative motors


  • According to IEC/EN 60255-1
  • Recognizes fuse failures in three-phase mains up to 3 AC 690 V
  • Can be used for all types and sizes of fuses
  • Independent of phase sequence
  • Shorter response time than with motor circuit-breakers
  • As option:
    - Energized on trip (output relay activated in the event of a fault)
    - De-energized on trip (output relay not activated in the event of a fault) with IP 9075 programmable via X4-X5 or X3-X4
  • As option with manual reset function and remote reset, programmable via X1-X2
  • 2 LED indicators
  • As option: 1 NO contact or 2 changeover contacts
