Application

RBK type fuse switch disconnectors are designed for power distribution and protection of electrical equipment against effects of short-circuit faults and overloads by use of industrial fuse links.

Operating conditions

  • to be installed in the room free of any dust, aggressive or explosive gases
  • for moderate, marine and tropical climate
  • altitude up to 2000 meters above sea level
  • outdoor – in cabinets with protection degree > IP 34
  • ambient temperature from -25°C to +55°C – but in case of use of disconnectors in temperature from +41°C to +45°C current value Ith should be reduced by 5% and within temperature range of +46°C to +55°C current value Ith should be reduced by 10%
  • for outdoors installation RBK fuse switch disconnectors should be mounted in cabinets with protection degree IP34 or higher

Construction

RBK fuse switch disconnectors consist of following parts:

  • three pole main base with spring-loaded contacts designed for connection of circular or sector-shaped cables, cables with lug terminals or busbars
  • detachable cover with fuse links
  • top protective contact cover with arc chutes, bottom protective contact cover

Thermoplastic parts of RBK fuse switch disconnectors are made of fibre glass strenghtened, flame retardant polyamide and polycarbonate. Silver plated contacts provide low power loss. Depending on clamp type, RBK fuse switch disconnectors enable user to connect circular or sector-shaped cables,cables with lug terminals or busbars.
