ARS evo / smartARS pro / ARS pro / RWS — LV strip-type fuse switch disconnectors up to 1 250 A, 690 V
Country: Poland · Model: ARS evo / smartARS pro / ARS pro / RWS
ARS and smartARS strip-type fuse switch disconnectors are fixed vertically on the busbars of a switchboard; they accept NH00–NH3 blade fuse links at 160–630 A and work at 690 V. They are installed in LV switchboards of transformer substations, cable cabinets, industrial switchgear and renewable-energy sites.

Description
The centre distance of the busbars can be 185, 100 or 60 mm. The ARS evo for NH00, NH1–NH2 and NH1–NH3 fuse links has a hinged opening, and the direction of outgoing cables can be changed from top to bottom. The smartARS pro series is designed for NH00 (160 A), NH1 (250 A), NH2 (400 A) and NH3 (630 A) fuse links; its housing is made of non-flammable self-extinguishing plastic of class V0, and the contacts are double-break. The smartARS-X pro and smartARS-XT pro versions have fuse blow monitoring modules SMW and SMR, and the smartARS P pro has current transformers built into the base that do not increase the dimensions. For a busbar bridge there is an IP20 version with a hook adapter, as well as the ARS 00/60 mm pro and ARS 00/100 mm pro. The main switch of a transformer up to 630 kVA is the ARS 630 kVA pro with NH3 gTr fuse links; for main circuits the ARS 1250 pro and RWS 600/750/1250 pro are used. The devices are designed to PN-EN 60947-1, PN-EN 60947-3, IEC 60947-1 and IEC 60947-3, and meet the requirements of Polish and European utilities.
How to choose
The device is selected by the fuse link size and the current of the outgoing line, and also by the busbar pitch of the switchboard. At solar plants with new-generation 800 V AC inverters, the smartARS pro-PV at 80, 200 or 400 A is installed, category AC-21B, 10 kA. When the line current has to be measured without extra space in the switchboard, take the smartARS P pro. For panel mounting in a cable cabinet the cassette-type RBK pro at 125–630 A is more convenient.

FAQ
What breaking capacity does the smartARS 00 pro have?
Conditional short-circuit current 80 kA at 690 V and 100 kA at 500 V. Utilization categories AC-22B at 690 V and AC-23B at 400 V.
Why are two thermal currents, 160 and 210 A, given for the smartARS 00 pro?
The value of 160 A applies to operation with a fuse link, and the device carries 210 A with blade links instead of fuse links.
How many operations does the smartARS 00 pro withstand?
Mechanical endurance is 1 600 cycles, switching endurance 200. Ui 1 000 V, Uimp 12 kV, frequency 50–60 Hz, protection degree IP30.
What are the parameters of the ARS 3 evo?
NH1–NH3 fuse links, thermal current 630 A, working current 400 A at 690 V. Conditional short-circuit current 100 kA at 690 V and 120 kA at 500 V, protection degree IP30.
