This product is mainly used on the export type meter to replace two single-phase relays. The outlet mode is 1 in 4 out, 2 in 3 out. The contact resistance can be controlled below 0.8 milliohms to meet UC3 and TUV requirements. The overall heating is low, and the temperature rises to 55K at a rated current of 100A. When the design phenotype is 80-90A current, the case temperature rise is better than the IEC standard. TUV certified ·IEC62055-31 UC3 (TUV)
For Prepayment energy Meter and AMR system Combination switch, reactive power compensation devices and automatic control.
