The ROK-6EM/B type switchboard may consist of the following distribution panels:
- incoming intended for powering the switchboard busbars,
- outlets designed to power and control receivers in a three-phase network,
- clutch switches designed to operate as a reserve switch between two sections of the switchgear busbars.
For all versions of distribution panels, there are versions with teletransmission equipment in various variants distinguished by an additional symbol in the version designation (/WM, /WD or /WS).
In flameproof distribution bays, high-quality e2TANGO microprocessor protection units and e2BRAVO, ROLLARC medium voltage circuit breakers or contactors were used in power circuits. The use of the above-mentioned switchgear and bay controllers ensures high functionality and a high level of service safety in the energy systems of methane mines.
