The switch is based on the original DW80-350 air switch. The switch, inheriting the advantages of the original air feeder switch of small size, light weight, convenient and flexible switch, adds the three-phase symmetry leakage protections of overload, short circuit, leakage atresia and total detection delay, and eakage protection. The protection device is a intelligent protector with a 16-bit single-chip as its core. There are electric closing switch and electric sub-gate.
