● Simple structure,few individual parts
Compact design,small size,low weight;
● Full function,high reliability
The orderly and centralized arrange of operating buttons and indicators;
● Easy maintenance
The whole mechanism or some parts can be replaced or repaired;
New technology-vacuum interrupter made in SIEMENS
● Low cut-off current,small contact resistance
● Rare contacts wear within long mechanical and electric life
● Contacts with axial magnetic field structure
Closed main circuit structure
● The vacuum interrupters are embedded in the insulation tubes,which can prevent from being damaged by the external factors.
● Special silicon rubber materials are used for reducing the vibration caused by circuit breaker operation.
● At the same time,it effectively interrupts the creepage of vacuum interrupter surface,thus reducing the volume of main circuit.
Vacuum interrupters&the operating device work together
With PRO-E software analysing and calculating,the integrated layout structure makes vacuum interrupters and the operating device work together in a good state.The test proves that the contact has less amount of wear.
Compact structure design
Few individual parts within circuit breaker,structure layout is rational.
It can fit fixedly or assemble with various draw-out switchgears such as KYN28,KYN79 type.
