Intelligent ZW32-12G Outdoor Vacuum Circuit Breaker 12kV

Intelligent ZW32-12G Outdoor Vacuum Circuit Breaker with Watchdog Controller

The ZW32-12G is a highly advanced outdoor pole-mounted vacuum circuit breaker equipped with an intelligent watchdog controller. Designed for modern power networks, it automatically isolates single-phase grounding and phase-to-phase short circuit faults at the line boundary, significantly minimizing the outage range. This unit is an essential asset for infrastructure upgrades, offering seamless SCADA remote control and auto-reclosing capabilities for enhanced grid reliability. We are a direct China manufacturer supporting bulk wholesale orders and customized configurations upon request.

Core Applications

This intelligent circuit breaker is heavily deployed in remote monitoring systems where automated fault response is critical. Key application scenarios include:

• Rural grid renovation and urban distribution automation.

• Overhead line protection and substation feeders.

• Optional metering applications, as the breaker can be equipped with current transformers (CT) for overload and short-circuit protection.

Key Technical Specifications

• Rated voltage: 12 kV

• Rated current: 630A / 1250A

• Rated short-circuit breaking current: 20kA / 25kA

• Rated short-time withstand current (4s): 20kA / 25kA

• Mechanical life: 10,000 operations

• Controller functions: Three-stage overcurrent protection, auto-reclosing (0-3 times), and remote measurement/control via SCADA.

Operational Advantages & Compliance

Engineered for strict environments, the ZW32-12G operates reliably across an operating temperature range of -40°C to +45°C. For projects requiring different specifications, we also supply the ZW32-12G featuring a reliable spring mechanism for overcurrent protection. By sourcing directly from our factory, contractors secure stable supply chains and rigorous quality compliance, as all units are fully compliant with IEC 62271-100 and GB/T 1984 standards.
