Feature: 1. SAFE AND FLAME RETARDANT MATERIAL: This automatic transfer switch is made of high-quality flame-retardant PC material, offering excellent insulation, high temperature resistance, and aging resistance. Silver contacts are used to enhance conductivity and extend the product's service life. 2. TWO OPERATION MODES: The power transfer switch supports both automatic and manual operation modes. It features a compact structure, reliable transmission, easy installation and maintenance, and a long service life. 3. 35MM STANDARD RAIL MOUNTING: This dual power automatic switch is a miniature household power switch designed for 35mm standard rail mounting. It is suitable for PZ30 distribution boxes and is primarily used to monitor the status of main and backup power supplies, ensuring continuous, reliable, and safe power delivery. 4. MILLISECONDS SWITCHING WITHOUT INTERRUPTION: The automatic transfer switch ensures seamless power transfer. In case of main power failure, the backup power supply activates immediately with switching time under 50ms, preventing power interruption. 5. APPLICABLE SCENARIO: Automatically transfers to the backup power supply during a power outage and reverts to the main power supply when power is restored. Suitable for 50 or 60Hz AC emergency power systems. Widely used in locations requiring uninterrupted power, such as factories, shopping malls, and nurseries.

The maximum ambient temperature should not exceed 40°C, the minimum should not be lower than 5°C, and the average temperature over 24 hours should not exceed 35°C. 2. The installation site altitude should not exceed 2000 meters. 3. When the ambient temperature is 40°C, the relative humidity should not exceed 50%. At lower temperatures, such as 5°C, higher humidity levels are permissible (e.g., 90% at 25°C). Appropriate measures should be taken to address possible condensation due to temperature fluctuations.
