Automatic 4P Dual Power Transfer Switch for Home AC230V 63A Coil

Features:1. MAIN PURPOSE: The automatic dual-power switch is primarily used to test whether the main or backup power supply is functioning correctly. It is DIN rail mounted and designed for use with a PZ30 distribution box.
2. GOOD PERFORMANCE: The switch is suitable for a 400V AC 50 or 60Hz backup power system. It features a robust structure, reliable switching, and convenient installation and maintenance.
3. APPLICABLE SCENES: Composed of a transfer switch and a controller, it is widely used in various situations where power outages cannot be managed and where electrical work or manual operation is required.
4. EXCELLENT MATERIAL: The use of flame retardant plastic, with good insulation, high temperature resistance, safe and reliable contacts, and silver contacts greatly improve the conductivity of the switch.
5. 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 meters 3. 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 changes in temperature
