Marking and Configuration
Applications of ABN203C-250A
- Supplying backup power: The 2-phase electric circuit breaker is used to automatically switch the power source between the main and backup sources when the main source fails or is interrupted. This ensures that devices and systems continue to operate normally in case of an issue with the main source.
- Automatic Control System: In automation applications and industrial control systems, the 2-phase electric circuit breaker can be used to switch between the main and backup power supplies to maintain stability and continuity of the system.
- Important and Security System: In some applications such as power stations, transformer stations, and security systems, the 2-phase electric circuit breaker ensures that these devices and systems are always ready to operate even when there is an incident with the main power supply.
- Medical System: In medical applications, especially in hospitals and healthcare facilities, the 2-phase electric circuit breaker can be used to provide backup power to essential medical equipment such as fire fighting machines, surgical machines, acupuncture machines,...
- Telecommunications System: In telecommunications systems, the 2-phase electric circuit breaker can be used to provide backup power to broadcasting stations, fiber optic stations, and other telecommunications equipments to ensure that telecommunications services continue to operate normally during a main power supply failure.
