Maximum current 32A, standby loss only 0.4 watts. Series installation device for mounting on DIN rail EN 60715 TH35. 1 module = 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 of active power is not measured and not 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 instantaneous consumption in watts. One phase 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 module 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 when powered.
