Only calibrated meters are approved for electricity billing according to §25 of the German Calibration Act. Non-compliance is an administrative offense under §19. M-Bus converter three-phase meter with adjustable converter ratio and MID. Maximum current 3x5A, standby loss only 0.5 watts per path. Rail-mounted device for installation on DIN-EN 60715 TH35 mounting rail. 4 division units = 70 mm wide, 58 mm deep. Accuracy class B (1%). With M-Bus interface. This three-phase meter measures active energy based on the currents flowing through the converters. The self-consumption of only a maximum of 0.5 watts active power per path is not measured and not displayed. 1, 2, or 3 converters can be connected with secondary currents up to 5A. The starting current is 10 mA. The neutral connection must be present. The 7-segment LC display can also be read twice within two weeks without power supply. The power consumption is indicated by a LED that blinks 10 times per kWh. To the right of the display is...
