AOU-40 2P Surge Protective Device

AOU

Characteristics

AOU surge protect Device, also known as lightning protector. It is an electronic device that provides safety protection for various electronic equipment, instruments and communication lines. When the electrical circuit or communication line suddenly produces a peak current or voltage due to external interference, the surge protection device can lead to shunt in a very short time, in order to avoid damage to other equipment in the circuit caused by the surge.AOU surge protector device is suitable for ac 50/60 Hz power supply system with rated voltage 220V/380V to protect indirect and direct lightning effects or other transient overvoltage surges. It meets the requirements of surge protection for residential use, tertiary and industrial fields.
