Intended use and application
The SPBP3R220 fuse disconnector is used in low-voltage installations as an apparatus to protect cables, lines and loads against overloads and short circuits using replaceable fuse links of 22 x 58 mm type. Three poles allow protection and disconnection of three-phase power circuits in apLications of industrial, commercial and infrastructure. The device is used in main switchboards, sub-switchboards, control cabinets and wherever safe and unambiguous disconnection of a circuit along with fuse protection function is required.
Design and functions
SPBP3R220 is a fuse switch/disconnector suitable for mounting fuse links of size 22 x 58 mm. The housing of the apparatus is made of insulating materials designed for use in low-voltage distribution equipment. The design ensures safe handling of fuse-links when manipulated and allows clear separation of current paths after disconnection. The disconnector is designed to meet the requirements of standards for disconnectors and fuse bases for low-voltage systems, taking into account high breaking capacity and resistance to heating caused by the flow of rated operating current.
ExpLoatation and safety
The device allows safe disconnection and switching of power circuits, provided that properly selected 22 x 58 mm fuse-links are used. Replacement of the inserts takes place after disconnecting the circuit and providing a visible insulation gap, which increases the safety of the operator. The disconnector can be used in an industrial environment with the appropriate degree of protection of the entire switchgear to which it is installed. The selection of conductor cross-sections, the method of connection and the parameters of fuse-links should be made in accordance with the manufacturer's documentation and applicable standards, so as to ensure proper selectivity of protection and limit the effects of short circuits and overloads.
