Maximum current 65A, standby loss only 0.4 watts. Modular device for mounting on DIN-EN 60715 TH35 rail. 1 division unit = 18mm wide, 58mm deep. Accuracy class B (1%). With S0 interface. This AC meter measures the active energy based on the current flowing between the input and the output. The internal consumption of only a maximum of 0.4 watts of active power is not measured and not displayed. 1 external conductor with a current of up to 65A can be connected. The starting current is 4OmA. If the load is expected to be more than 50%, a ventilation distance of 1/2 division unit from devices mounted next to it must be maintained. Use the DS12 spacer if necessary. Two N terminals for the safe cross-wiring of several meters. The 7-segment LC display can also be read twice within two weeks without a power supply. To do this, press the button. There is a button below the display that is used to scroll through the menu according to 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 active power, voltage and current can be displayed. The power consumption is shown in the display with a bar that flashes 1000 times per kWh. Error message: If there is a connection error, the background lighting of the display flashes.
