Fuse Monitor
RN 9075

The fuse monitors RL 9075 and RN 9075 of the varimeter series monitor up to 3 fuses. The measurement is very simple and without extensive wiring, as no separate auxiliary supply is necessary. The fast detection of a defective fuse protects against expensive damages and the user has the benefit of high operational performance and availability of the plant.

Advantages
. Increasing the availability of plants by early detection of blown fuses, that may cause damage if undetected
. Fast detection of blown fuses also with disconnected load availability of your plant on request
. Reliable detection of blown fuses inspite of:
- asymmetric mains
- harmonic content
