1.DS802C 50A is mainly used on export-type watches to replace two single-phase relays. The outlet mode is 1 in 2 out, 3 in 4 out. 2.The contact resistance can be below 0.8 milliohms for a long time, reaching UC2, UC3, and TUV requirements. 3.The overall heating condition is 50K at a rated current of 60/90A. TUV approval
For Prepayment energy Meter and AMR system Combination switch, reactive power compensation devices and automatic control.
