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

Measuring range max.: 440 V
Standard measuring range: 3 AC 380 - 415 V
1- / 3-phase: 3
Output contacts: 1 NO contact, 2 C/O contacts
Width: 35 mm
Enclosure design: Switch cabinet
Type: SL 9075

Advantages

  • 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
