Maximum current 3x80A, standby loss only 0.5 watts per path. Modular device for mounting on DIN rail EN 60715 TH35. 4 division units = 70 mm wide, 58 mm deep. Accuracy class B (1%). With S0 interface. The directly measuring three-phase energy meter measures active energy based on the currents flowing between the inputs and outputs. 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 external conductors with currents up to 80A can be connected. The inrush current is 40 mA. The neutral connection must be present. The 7-segment LC display can also be read twice within two weeks without power supply. Power consumption is displayed with a bar that blinks 100 times per kWh. Standardly usable as a 2-tariff meter: by applying 230V to terminals E1/E2, it switches to a second tariff. To the right of the display are the MODE and SELECT buttons.
