Find out what the smartARS-XT pro fuse switch disconnector, SMR version, has to offer

The smartARS-XT pro fuse switch disconnector can be fitted with a device that indicates the current status of the fuse links. Information regarding blown fuses, correct operation or loss of voltage is indicated by appropriate LED signals or can be transmitted to a master system directly from the module via an RS-485 interface using the MODBUS communication protocol.

Applications of the smartARS-XT pro fuse switch disconnector

Transformer stations

The fuse switch disconnectors in transformer substations ensures the highest standards of operational safety. The design of the switchgear allows for rapid disconnection of the power supply. Furthermore, its resistance to harsh conditions and temperature fluctuations means the equipment does not require frequent servicing, thereby reducing operating costs.

Low voltage switchgear

The fuse switch disconnector is a solution designed to optimise space in LV switchgear. Thanks to its compact design, it facilitates the arrangement of equipment whilst ensuring reliable circuit protection. A well-designed connection system allows cables to be neatly and safely routed, which speeds up installation and makes future inspections easier.

Cable connectors

The fuse switch disconnector ensures effective circuit isolation, thereby enhancing staff safety during operational work. Furthermore, the device minimises the risk of phase-to-phase short circuits, and its design guarantees the stability of the network parameters.
