Automatic two-pole switch NSX100NA (LV429619)
Article number (Catalog number):
LV429619
Name:
2-pole disconnector switch (load switch) NSX100NA for currents up to 100 A
Application:
The NSX100NA switch-disconnector is used in power switchboards, intermediate switchboards, local partitioning boards, small-sized switchboards and automation boards in energy saving buildings, final distribution, continuous technological processes, as well as in the technological processes of a separate machine (machine)
Appointment:
The main functions of the NSX100NA load switch:
- connection and partitioning of busbars
- connection of the prefabricated panel and automation cabinets
- connection of the intermediate switchboard
- connection of local partitioning boards
- connection of small-sized switchboards
- switch-disconnector of automation panels
Execution:
2-pole device in a 3-pole housing
The power part of the Compact NSX-100NA circuit breaker with an operating voltage of up to 690 V AC and a current of up to 100 A
Stationary device assembly with front connection
With the NA load switch unit installed
Automatic control - manual, lever
Mounting on a panel/board/metal structure with screws, on a DIN rail or a 3-pole 60 mm bus through appropriate adapters
Ensuring guaranteed disconnection according to IEC 60947-3 standard:
- mechanical reliability of position indicators: the position "O" (OFF - "off") unambiguously reflects the open position of the contacts, observing the necessary gap between the contacts and the possibility of blocking, if only the contacts are really open
- no leakage currents
- resistance to overvoltage on the circuit layout between the source and the load
- maintaining guaranteed disconnection when installing a rotary handle or a gear motor on the disconnector switch

- Pole spacing: 35 mm without expander and 45 mm with pole expander
Cable lugs
- Models: for aluminum and for copper cables
- mandatory joint use with pole separators or with long terminal plugs
- connection cables: copper cables with a cross section of 120/150/180 mm2 with crimping hexagonal stitching or stamping or aluminum cables with a cross section of 120/150/180 mm2 with crimping hexagonal stitch
Additional contact plates(mounted on standard contact plates)
- contact plates-extension cords
- angular contact plates
- contact plates on the "edge"
- double angled contact plates
