.908B 100A is mainly used on export-type watches to replace two single-phase appliances. 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 TUV requirements. The overall heating condition is 50K at a rated current of 100A. When the phenotype is designed to be 80-90A, the case temperature rises to the ICE standard. .TUV Approval More than 3 million sets of this symmetrical phenotype
For Prepayment energy Meter and AMR system Combination switch, reactive power compensation devices and automatic control.Two pole/phase relay
