4P 125A 400V Add Firefighting Function

4P 125A 400V Add Firefighting Function is mainly used in the need for dual power supply, or even multi-power supply protection in the electricity environment, the main function of this product is that when the main power supply fails, the load can be quickly switched to the standby power supply through a reliable switching mechanism. In particular, this switch can be installed with a power generator from the start function, further improving the emergency power supply system, enhance the ability to respond to sudden power outages.

Generator Power Auto-start Function Expansion:
This YRO transfer switch can be flexibly equipped with the generator power auto-start function. Before adding this function, the generator power needs to be kept on all the time. Although this is the safest approach, it may cause unnecessary wear and tear. However, after adding this function, the generator power can be turned off. When the main power fails, the ATSE can automatically send a signal to the generator, triggering it to start on its own and connect to the power supply, efficiently ensuring the continuous supply of electricity, and avoiding the impact on important equipment and work caused by power outages.

Compliance with IEC 60947-6-1 Standard:
The YRO 4P 125A 400V Add Firefighting Function with the IEC 60947-6-1 standard. This standard has strict regulations on the product's safety performance, including aspects such as electrical insulation, mechanical strength, and fire protection. From this perspective, this transfer switch can largely ensure the safety of users during the usage process, and reduce the risk of accidents caused by electrical faults.

1. Clear applicable environment: YRO identifies the precise temperature range of the switch, which is designed to help customers easily determine whether it can meet the specific local working environment conditions. This is important for outdoor working areas, as well as those with significant temperature fluctuations, and provides a key reference for stable operation of the equipment.
2. Ensure equipment performance: Knowing the frequency range of ATS can help users determine whether it is suitable for a specific power system. If the frequency range of the ATSE does not match the user's power system, it may cause the performance of the device to degrade or not work properly. Therefore, the display of this parameter helps customers choose the right equipment to ensure the stable operation of the power system.
