Application:
- Backup power supply: 2-phase circuit breakers are used to automatically switch power supply between the main and backup power when the main power has a problem or power failure. This helps ensure that critical equipment and systems continue to function normally in the event of a problem with the main power.
- Automatic control system: In automation applications and industrial control systems, 2-phase electrical circuit breakers can be used to switch between main and backup power supplies to maintain system stability and continuity.
- Critical systems and security: In critical applications such as power stations, substations, security protection systems, 2-phase circuit breakers ensure that these devices and systems are always ready to go even if there is a problem with the main power supply.
- Medical systems: In medical applications, especially in hospitals and medical facilities, 2-phase circuit breakers can be used to provide backup power to critical medical equipment such as fire extinguishing machines, surgical machines, acupuncture machines, etc.
- Telecommunication system: In telecommunication systems, 2-phase circuit breakers can be used to provide backup power to base stations, fiber optic stations, and other telecommunication equipment to ensure that telecommunication services still operate normally when there is a problem with the main supply.
