CT operated energy meter with settable CT ratio and MID. Maximum current 3x5A. Standby loss 0.4 watt per path only. Modular device for DIN-EN 60715 TH35 rail mounting. 4 modules = 70mm wide and 58mm deep. Accuracy class B (1%). With S0 interface. This three-phase energy meter measures active energy by means of the current between input and output. The internal power consumption of 0.4 watt active power per path is neither metered nor indicated. 1, 2 or 3 phase conductors with max. currents up to 5A can be connected. The inrush current is 10mA. The N terminal must always be connected.
