● 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.

Extensive application

It can fit fixedly or assemble with various draw-out switchgears such as KYN28,KYN79 type.
