Applications of the ARS 1250 pro isolating switch

Transformer stations

The use of strip-type 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 switchgears

The strip-type 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 strip-type 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.
