ZN28G-12/630A integrated high-voltage vacuum circuit breaker inside the cabinet

The ZN28G-12 indoor vacuum circuit breaker is an indoor high-voltage switching equipment with a rated voltage of 12KV and three-phase AC 50HZ. It is mainly used for the control and protection of power transmission and distribution systems in power plants, substations and other occasions, and is especially suitable for places with frequent operations. This equipment model is ZN28G-12, which adopts a spring energy-storage operating mechanism. This circuit breaker adopts a composite insulated overall structure in which the vacuum interrupter and the operating mechanism are arranged front and rear, and has the characteristics of small overall size, low energy consumption and low noise. It does not need adjustment and has low maintenance workload. The vacuum interrupter includes two types of ceramic and glass, and realizes opening and closing operations through the high vacuum insulation performance and special contact structure, with advantages such as strong breaking capacity, long service life and no explosion hazard. Its serialized and miniaturized design can be adapted to central switchgear and fixed switchgear to meet the needs of different customers.

● The ZN28G-12 series vacuum circuit breakers are indoor high-voltage switching equipment with a rated voltage of 12KV and three-phase AC 50HZ.● This vacuum circuit breaker has a simple structure and small size. The operating mechanism is of spring energy-storage type. It can be operated by AC or DC. Up to three over-current trip devices can be installed. The vacuum interrupter part and the operating mechanism part are arranged front and rear, with a composite insulated overall structure, small overall size, low energy consumption, low noise and easy installation. No adjustment is needed and maintenance is extremely rare.● The vacuum interrupter has two types of ceramic and glass. It uses the high insulation performance of vacuum and the specially designed contact structure to complete opening and closing operations, with strong breaking capacity, long service life and no explosion hazard.● This vacuum circuit breaker can be used for the control and protection of power transmission and distribution systems in power plants, substations and other occasions, and is especially suitable for places with frequent operations.● This vacuum circuit breaker has complete specifications, is serialized and miniaturized. It can be used alone or in central switchgear and fixed switchgear to meet the needs of different customers.
