Distribution cabinets series PR

Purpose and scope

The cabinets are designed to distribute electrical energy and protect electrical installations during overloads and short circuit currents, for infrequent (up to 6 per day) operational switching on and off of electrical circuits and starts of asynchronous motors in networks with a rated voltage of up to 660 V AC, frequency 50 and 60 Hz - PR 8503 and voltage up to 220 V DC - PR 8703. Cabinets can be used in all types of electrical networks in terms of grounding (according to GOST R 50571.3) with various options for the location of the zero working and zero protective conductors.
