Switchgear Components, Surge Protection and Control Gear for Electrical Contractors

This category collects the working parts of low and medium voltage networks: 2,895 positions from 363 suppliers. The consumer-facing end includes 592 sockets, switches and wall plates; the engineering end runs through 259 surge protection devices, 222 grounding and earthing bars, 207 push buttons and control switches, 194 RCDs and RCBOs, 192 distribution boards, 132 contactors and motor starters, protection relays, electromechanical and solid-state relays, pilot lights — and, at the heavy end, 92 high voltage vacuum circuit breakers. A 242-listing block of fire and security detectors and sounders rounds out the building-safety side.

Russian electrotechnical plants build for networks where voltage spikes, unstable grounding and dust are routine, so components carry conservative ratings and wide climatic executions — the UHL marking system explicitly defines temperature and humidity classes. For panel builders and electrical wholesalers in markets with similar grid behaviour, this is equipment engineered for their actual conditions rather than laboratory ones.

  • Compatibility: DIN-rail form factors and IEC-aligned ratings integrate with standard panel layouts.
  • Wholesale lots: modular devices from carton quantities; vacuum breakers and relay protection from single units.
  • Climatic versions: temperate, cold and tropical executions specified at order.
  • Documents: EAC declarations, type test reports and English datasheets for tender files.

Send the bill of materials from your panel project and suppliers will quote with delivery to your port or border point.

FAQ

Will these components fit standard DIN-rail panels and IEC layouts?
Yes. Modular breakers, RCDs, contactors and relays follow standard DIN-rail mounting and IEC-style module widths, so they install in common enclosure brands without adaptation. Ratings are marked in the same ampere and kiloampere series used internationally. For mixed panels, request dimensional drawings to confirm busbar and comb compatibility.
Can panel builders order OEM or co-branded components?
On recurring volumes, plants apply the panel builder's marking to device fronts, labels and packaging, typically from several hundred units per SKU. Certification continues to reference the manufacturer. Some factories also assemble complete boards to your single-line diagram, shipping tested panels instead of loose components.
What do the climatic execution codes like UHL1 mean for my market?
Russian products carry GOST 15150 climatic codes defining ambient ranges: UHL covers moderate and cold climates, T marks tropical execution with humidity and mould resistance, and the digit states placement from outdoor to heated indoor. Specify a tropical or general climatic version when ordering for the Gulf, Africa or humid coastal regions.
Are surge protection devices coordinated by class?
Yes, SPDs are offered in Class I, II and III per the IEC 61643 classification, with coordination tables for cascading from service entrance to socket level. Suppliers will propose a coordinated set if you describe the installation: building type, lightning exposure and the sensitivity of connected equipment. Test reports accompany each model.
What warranty and failure handling applies to protection devices?
Manufacturers typically warrant modular devices for 2–5 years from sale. Failed units under warranty are replaced rather than repaired; claims need the device, batch code and a short failure description. For relay protection and vacuum breakers, plants offer extended support including spare modules and remote diagnostics by agreement.
How quickly can a wholesale order be assembled and shipped?
Popular modular devices ship from factory stock within 1–2 weeks. Vacuum circuit breakers, protection relays and non-standard climatic executions are produced to order in 4–8 weeks. Consolidated cargo trucks to Central Asia in 7–14 days; sea routes via Novorossiysk or St. Petersburg add 25–45 days depending on destination.
