Feature: 1. MAIN PURPOSE: Dual power automatic switch is mainly used to test whether the main power supply or backup power supply is normal, rail mounting, dedicated to PZ30 distribution box. 2. GOOD PERFORMANCE: The switch is suitable for 50 or 60Hz rated 400V AC emergency power supply system, with firm structure, reliable conversion, convenient installation and maintenance. 3. APPLICABLE SCENES: Composed of transfer switch and controller, widely used in various situations that can not withstand power failure and can rely on electrical work or manual operation. 4. EXCELLENT MATERIAL: Using flame retardant plastic, with good insulation, high temperature resistance, safe and reliable, and silver contacts greatly improve the conductivity of the switch. 5. UNINTERRUPTED POWER: When the normal power supply is abnormal, the backup power will work immediately without interruption to ensure the continuity, reliability and safety of the power supply.

Package List: 1 x Automatic Transfer Switch1 x User Manual Note: 1. The maximum ambient temperature should not exceed 40℃, the minimum should not be lower than ‑5℃, and the average temperature within 24 hours should not be higher than 35℃2. The altitude of the installation site should not be higher than 2000 meters3. When the maximum temperature reaches 40℃, the relative humidity of the installation site should not exceed 50%; when the temperature is the lowest temperature of ‑5℃, the relative humidity is higher, for example, if the temperature is 25℃, the relative humidity is 90%. Special measures should be taken to deal with occasional condensation on product surfaces due to temperature changes
