Feature: 1. Power Transfer Switch: The dual power automatic transfer switch is a miniature household power switch, which is mainly used to test whether the main power supply or standby power supply is normal, so as to ensure the continuity, reliability and safety of the power supply. 2. Quick in Switching: When the normal power supply is abnormal, the standby power supply will work immediately to ensure the continuity, reliability and safety of power supply, and millisecond level switching can achieve the effect of continuous power supply. 3. PC and Silver Contact: Premium flame retardant PC material is used, with good insulation, high temperature resistance, aging resistance, safety and reliability. The use of silver contact can greatly improve the conductivity and service life of the switch. 4. Wide Application: Switch to the standby power supply in case of power failure, and switch to the main power supply when power restores. It is widely used in various places where continuous power failure is not allowed, such as factories, shopping malls, nursery farms, etc. 5. Compact Design: The ATS has compact structure, reliable transmission, convenient installation and maintenance, and long service life. Specially designed for household rail mounted installation, specially used for PZ30 distribution box.
