The PCIR-01 device is an indicative means of monitoring the insulation value of the cable line in relation to the normalised value of 360 kΩ and does not allow switching on the circuit breaker in case of reduced or broken insulation of cable lines and electrical receivers.

The PCIR-01 device can be operated as a device that allows automatic reclosing of the circuit breaker in case of non-selective disconnection of the connection from the power supply system, provided that the required insulation level is maintained.

The device is intended for use as part of complete switchgear (KRP), mobile switchgear of class 6 (10) kV used for power supply to consumers, including consumers of underground workings (in the normal mine version), which have permission for use in the relevant operating conditions, and corresponds to the placement category.

The climatic design is determined in accordance with DSTU and the climatic design of the complete device (integrated system).
