Horizontal Fuse Switch Disconnect
Construction
- Thermoplastic parts of RBK pro fuse switch disconnectors are made of fibre glass strengthened polyamide with halogen free flame retardant added and have highest possible flammability class – V0
- RBK pro fuse switch disconnectors consist of the following parts:
- Three pole main base with spring-loaded contacts designed for connection of circular or sector-shaped conductors, and conductors with lug terminals or bars
- Removable cover with fuse links
- Arc chambers with steel deionization plates over top contacts
- Silver plated contacts providing low power loss
Mounting
- On mounting plate
- RBK 000 pro
- RBK 00 pro
- RBK 1 pro
- RBK 2 pro
- RBK 3
- DIN rail
- Single: RBK 000 pro
- Double: RBK 00 pro
- On to busbar systems:
- 60 mm RBK 000 pro-S, RBK 00 pro-S, RBK 1 pro-S, RBK 2 pro-S, installation on to busbar system with hooked clamps, placed inside fuse
- 60 mm RBK 3-S installation on busbar system using adapter with three M10 screws
- 100 mm (RBK 2-S, RBK 1 pro-S) installation on to busbar system with hooked clamps placed inside fuse
Operating Conditions
- To be installed in the room free of any dust, aggressive or explosive gases
- Altitude up to 2000 meters above sea level
- Outdoor – in cabinets with protection degree > IP 34
- Ambient temperature from -25 °C to +55 °C
- Relative humidity of the air should not be higher than 50% at temperature of +40°
Functionality
- Making and breaking operations should be done with determined movement
- Possible connection of circular or sector-shaped conductors with bare ends (V-terminals, 2V-terminals) or conductors with lug terminals (screw terminals)
- Voltage test performed through test holes in fuse link cover
- Fuse links state monitoring
