APPLICATIONS
Designed for distribution of electricity and protection of electrical equipment against short-circuits and overloads with industrial fuse links. RBK pro fuse switch disconnectors are designed for distribution of electricity and protection of electrical equipment against short-circuits and overloads with industrial fuse links. They are conforming to EN 60947-1, EN 60947-3, IEC 60947-1, IEC 60947-3 standards. They are intended for installation in low voltage distribution boards, cable and metering cabinets.
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 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.
