GEYA W2R-4P Automatic Changeover Switch for PV

GEYA W2R-4P Automatic Changeover Switch is a newly developed miniature household power transfer switch. This switch is mainly used to test whether the normal or standby power supply is normal. When the normal power supply is abnormal, the backup power supply will work immediately to ensure the continuity, reliability, and safety of the power supply. This product is specially designed for home track TV installation and is specially used for the Pz30 distribution box.

Complies with requirements of Low-voltage Switch Gear and Control Gear specified by IEC 60947-6-1 and IEC60947-3: functional equipment and transfer switch equipment
