Overview of ZW32 Outdoor High Voltage Alternating Current Vacuum Circuit Breaker

ZW32 Outdoor High Voltage Alternating Current Vacuum Circuit Breaker is a type of circuit breaker where the arc quenching medium is a high vacuum. Unlike older breakers that used air, oil, or SF6 gas to extinguish the electrical arc, a VCB utilizes the superior dielectric properties of a vacuum to rapidly extinguish the arc when the contacts separate, thereby interrupting the current flow and protecting the electrical system.

Characteristics of ZW32 Outdoor High Voltage Alternating Current Vacuum Circuit Breaker

Strong arc extinguishing ability: using vacuum medium to quickly extinguish the arc, with high breaking ability.

Safe and environmentally friendly: No fire or explosion risks, no greenhouse gas emissions.

Easy maintenance: Vacuum bubbles are maintenance free, with a long overall maintenance cycle and low workload.

Long lifespan: Both mechanical and electrical lifespan are very long.

Small size: Compact structure, saving space.”

Specifications of ZW32 Outdoor High Voltage Alternating Current Vacuum Circuit Breaker

Here’s the ZW32 Outdoor High Voltage AC Vacuum Circuit Breaker specifications. This device handles high voltage electricity safely outdoors. It uses vacuum technology to stop electrical faults quickly. The rated voltage is 12 kilovolts or 24 kilovolts. The highest system voltage reaches 12 kilovolts or 24 kilovolts also.

The breaker manages large currents. Its rated normal current goes up to 1250 amperes. The rated short-time withstand current is 20 kiloamperes or 25 kiloamperes. This current lasts for four seconds. The rated peak withstand current hits 50 kiloamperes or 63 kiloamperes. The rated short-circuit breaking current matches the withstand current. It breaks this fault current reliably.

Insulation is crucial. The power frequency withstand voltage is 42 kilovolts or 65 kilovolts dry. It withstands 30 kilovolts or 37 kilovolts wet. The lightning impulse withstand voltage is 75 kilovolts or 125 kilovolts. These levels protect against surges.
