Can the RM6 take DIN type fuses other than FUSARC ?

Thanks to consult us on a case by case basis. RM6 is designed to accept any DIN cut-out MV fuses provided that their electrical characteristics (rating, cold resistance, thermal dissipation, time-current curves...) are in compliance with RM6 fuse-switch combination performance.
Maximum power that can be dissipated by fuse is 80W (with 40°C maximum ambient temperature)

Transition current for RM6 is :

-*- 1750A at 12kV

-*- 1550A at 17.5kV

-*- 1050A at 24kV

Breaking time of RM6 fuse-switch combination is 60mSec.

It should be borne in mind that 2 DIN fuses made by different manufacturers and with same nominal current rating can have totally different electrical characteristics : cold resistance, time-current time, striker-pin power,...

Basically, we only guarantee correct operation of RM6 combined with Fusarc CF.
