Maximum current 32A, standby loss only 0.4 watts. Modular device for mounting on DIN rail EN 60715 TH35. 1 division unit = 18 mm wide, 58 mm deep. Accuracy class B (1%). With S0 interface. This AC meter measures active energy based on the current flowing between the input and output. The self-consumption of only a maximum of 0.4 watts active power is not measured or displayed. Like all meters without MID conformity declaration, it is not approved for monetary electricity billing in Europe. Every 30 seconds, the display switches for 5 seconds from the accumulated active energy in kWh to the current consumption in watts. One external conductor with a current of up to 32A can be connected. For an expected load of more than 50%, a ventilation distance of 1/2 division unit must be maintained from adjacent mounted devices. If necessary, use the spacer DS12. The starting current is 20 mA. The display can only be read with power supply.
