Only calibrated meters are permitted for electricity billing according to paragraph 25 of the German Calibration Act. Failure to comply is an administrative offence according to paragraph 19. Transformer-based three-phase meter with adjustable transformer ratio and MID. Maximum current 3x5A, standby loss only 0.5 watts per path. Series-mounted device for mounting on DIN-EN 60715 TH35 mounting rail. 4 division units = 70mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. This three-phase meter measures the active energy based on the currents flowing through the transformers. The internal consumption of only a maximum of 0.5 watts of active power per path is not measured and is not displayed. 1, 2 or 3 transformers with secondary currents of up to 5A can be connected. The starting current is 10mA. The N connection must be present. The 7-segment LC display can be read twice within two weeks even without a power supply. The power consumption is shown in the display with a bar that flashes 10 times per kWh. To the right of the display are the MODE and SELECT buttons, which are used to scroll through the menu as per the operating instructions. First, the background lighting switches on. Then the total active energy, the active energy of the resettable memory and the instantaneous values of power, voltage and current for each outer conductor can be displayed. The converter ratio can also be set. It is set to 5:5 at the factory and locked with a bridge over the connection terminals marked JUMPER. The converter ratio is adapted to the installed converter by removing the bridge and resetting it as per the operating instructions. It is then locked again with the bridge. The converter ratios 5:5, 50:5, 100:5, 150:5, 200:5, 250:5, 300:5, 400:5, 500:5, 600:5, 750:5, 1000:5, 1250:5 and 1500:5 can be set. Error message (false): If the outer conductor is missing or the current direction is incorrect, false and the corresponding outer conductor are shown in the display. Attention! Before working on the current transformers, disconnect the meter's voltage paths.
