ZW32 is a three-phase structure, each phase is combined of vacuum interrupter and operation insulator in the sealed pole. The permanent magnet mechanism adopts three-phase linkage, mounted in a sealed stainless steel shell. Enclosure is with IP65. There are breather with prevent condensation unit at the bottom of the shell.
The magnetic mechanism is with interlock function to keep the operation of mechanism in good condition and keep the ON/OFF condition by electromagnetic lock. Tripping is done by an anti power of coils from an anti current .The operation power is supplied by the capacitor in the Recloser Control.
ZW32 Automatic circuit breaker is with manual tripping function to keep the automatic circuit breaker at ON/OFF positions by handle the handshank out of the shell which is with indication ON/OFF ,it is easy for operator to watch conditions from the ground., the automatic circuit breaker‘s ON/OFF can be inspected by state of auxiliary switch .by current transformer of which rate is 600/1A(100-500/1A optional)CT to meter current and protect the over-current .The main insulated pole is poly insulating material which is anti-ultraviolet rays. The silicon rubber tube of outlet is with high creep distance .the terminal kit is 70x40x8mm T2Y tinned copper kits to connect with connector and over head line.
