Product feature

Flexible operation, convenient:

this product can be electric energy storage, electric switch, can also be hand machine, manual, switching function, and can be close or far away from the remote control;

Open circuit performance is superior, the breaking short circuit current of 25 ka for 30 times;

Operating power is small, high reliability: the new design of miniaturized electric spring mechanism, part number and energy-storage motor is rated power (around 40 w) reduce to the lowest level; Flexible installation, can be used in a column on lifting or sit installations;

Maintenance-free characteristics: the main loop of the circuit breaker, the secondary components, operating mechanism are sealed in the SF6 gas pressure (zero table),not influenced by the external environment, stable performance, reliable, free maintenance;
