Protection: Overcurrent,overload, phase loss, over voltage etc
Measure volt, amp, watt, kwh etc
Profibus/Modbus

Product characteristics

Perfect current and voltage protection function; Perfect measuring functions and available to offer full electric quantity monitoring; Perfect control functions; with the DCS control system, it can offer various start-stop control on various motors; LCD display, easy to check from the man-machine interface;Stable operation, without needing maintenance works required by the conventional thermal relay. With 4~20mA analog quantity output and RS485 and Profibus(230)communication interface, it offers an executive platform for smart low-voltage power distribution network. The MMPR-200 adopts the separable structure and rail-base installation mode.
