Only calibrated meters are approved for electricity accounting according to §25 of the German calibration law. Non-compliance is an administrative offense according to §19. Maximum current 3x80A, standby loss of only 0.5 watts per path. Series installation device for mounting on DIN-EN 60715 TH35 mounting rail. 4 division units = 70mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. The direct measuring three-phase meter measures the active energy based on the currents flowing between the inputs and outputs. The own consumption of only a maximum of 0.5 watt active power per path is not measured and not displayed. 1, 2 or 3 external conductors with currents up to 80A can be connected. The starting current is 4OmA. The N connector must be present. The 7-segment LC-display can be read twice within two weeks even without power supply. The power consumption is indicated by a bar flashing 100 times per kWh in the display. Can also be used as a 2-tariff counter as standard: When 230
