Description

The ZW32-12M series outdoor High Voltage Permanent Magnetic Vacuum Circuit Breaker is designed for use in three-phase electric systems operating at an AC frequency of 50 Hz and a rated voltage of 12kV. This advanced circuit breaker is ideal for breaking and closing load currents, handling overload conditions, and protecting against short-circuit currents. It is perfect for substations, industrial mining enterprises, or rural electrical power distribution systems.

Main Functional Characteristics:

• Automatic Control Function: Features switching status control, three-section overcurrent protection, and three auto-reclosure capabilities, along with an RS-485 communication connector for remote measurement, adjustment, control, and communication, making it suitable for automated power distribution systems.
• Permanent Magnetic Mechanism Operation: Utilizes an advanced permanent magnetic mechanism that ensures minimal abrasion of spare parts, achieving a lifespan of up to 30,000 operations—three times longer than conventional spring mechanisms. This design reduces machinery spare parts by 70%, enhancing the reliability of the switching process.
• Full-Sealed Structure Design: The vacuum interrupter, operational mechanisms, and linkage are sealed within the vacuum circuit base, preventing condensation and allowing for maintenance-free operation for up to 10 years.
• Miniaturized Structure: Incorporates a new type of compound solid insulating material, allowing the vacuum interrupter, main galvanic circuit, and isolation support to form an integrated embedded pole, effectively resolving the conflict between miniaturization and external isolation requirements.
