Ningbo Doto Electric Co., Ltd.
MR is a tape-wrapped ring-type (toroidal) current transformer for through-type primary currents from roughly 100 A to 600 A. The fully encapsulated epoxy-tape winding resists moisture and vibration, the primary cable simply passes through the centre window, and the two secondary terminals with stud fixings make wiring to meters and relays straightforward. It is a robust, low-cost choice for motor control centres, generator sets and switchboard metering.
