Visión general
FZN25, FZRN25 tipo meseta de vacío interruptor de carga y aparatos eléctricos de combinación, adecuado para trifásica AC 50Hz anillo de red o terminal de alimentación y equipos eléctricos industriales, para el control de carga y protección contra cortocircuitos, carga de conmutación del interruptor de carga, corriente de bucle cerrado, transformador sin carga y cable de carga de corriente, aparatos eléctricos de combinación se puede romper hasta cualquier corriente nominal de cortocircuito, de acción directa fractura de aislamiento y vacío interruptor de enlace se adoptan. Tiene funciones manuales y eléctricas.
FZN25, FZRN25 plateau type vacuum load switch and combined electrical appliances have high temperature resistant, strong insulation, and fl ame retardant transparent glass cover between the static contact and the moving guide torch, effectively ensuring the safe operation of equipment and personal safety. The load switch and ground switch are equipped with reliable mechanical interlocking, which not only ensures safety but also facilitates maintenance.
Structural Characteristics
The switch has a real sense of double fracture design, the overall installation than ZFN21 and other types of vacuum series switch has simple design, convenient installation, simple and efficient debugging, small size, low cost characteristics, to avoid other types of switch accessories, installation complex lock, debugging is not easy, has great cost-effective advantages. The switch can come with sensors and displays, which can save considerable material and manufacturing costs for users such as complete sets of companies, and has great market promotion value.
The switch with sensor and display series products are used in cable branch boxes, which can effectively save space and greatly reduce the volume of outdoor boxes. Greatly reduce the production cost.
