main feature
The outer casing is made of stainless steel, which has reached a permanent use of corrosion resistance requirements.
Increase the explosion-proof pressure relief device to avoid circuit breaker cracking due to the increase in arc fault pressure of the switch
The input and export terminal can be modified into an insulated cable type to effectively avoid the phase flashing failure caused by foreign factors.
Installing a low gas pressure locking device, allowing the gas pressure in a dual control state, improve the reliability of the switch operation
Change the entry and exit end cover to an organic insulator shape, completely eliminate the rupture of the porcelain bottle caused by external force and lightning and the crack caused by porcelain factors, greatly improve the reliability of the circuit breaker operation.
Installing a manual locking device, effectively preventing errors when power outage
The phase distance between the switch is increased to 250mm, which can greatly reduce the flash drive, short circuit fault.
