Product Datasheet

Approvals

Input switching device (ISD) provides protection against short circuits, overloads and leaks in power supply systems with rated voltages up to 380 V, frequency 50 Hz with dead-earthed neutral. Used for input, metering and distribution of power, for infrequent switching of electrical circuits.

ISD is assembled from the single-side maintenance sections in metal cabinets. ISD can consist of one or more floor-mounted cabinets. When connecting ISD to two independent power sources, it is possible to assemble ISD input panels with an automatic switch in one cabinet with a partition between the sections. ISD is assembled with automatic circuit breakers, meters and other equipment depending on the terms of reference.
