Pre-prepared substation marked R-AC-25 meeting the requirements of ČSN EN 60670. In the substation we find a contactor combination that switches to backup mode in case of a mains failure. As soon as the supply from the grid is restored, the substation automatically switches to on-grid mode. The whole house is connected to the substation, so all circuits in the house are backed up. There is a slight time delay when the contactors are switched. The substation is pre-prepared for the installation of smartmeter and current transformers.

The substation includes:

(1pc) Plastic switchboard for wall mounting - 4 rows, 48 modules, transparent door Noark
(1pc) Main circuit breaker 3P B25A Noark
(1pc) Surge arrester T1+T2 (B+C), 4P 12.5kA Noark
