FAQ
Q: What is the difference between ZW32 and ZW20 circuit breakers?
A: While both are outdoor vacuum circuit breakers, the ZW32 model typically features a more advanced operating mechanism and is often preferred for its higher reliability in automated distribution systems. The ZW20 is known for its flexible installation options (hanging or sitting), while the ZW32 usually adopts a fixed mounting style for stability.
Q: Can this breaker be controlled remotely (SCADA/RMU)?
A: Yes, the ZW32-12 is designed to integrate with distribution automation systems. It can be equipped with a remote control module (RTU) to enable SCADA monitoring and operation, allowing you to manage your grid from a central location.
Q: What is the warranty period for this product?
A: We offer a standard 24-month warranty. Additionally, with a mechanical life of 10,000 operations, this breaker is built for long-term, maintenance-free service in outdoor environments.
Q: Do you provide customization (OEM/ODM)?
A: Absolutely. As a factory, we support OEM services. We can customize the color, nameplate, and specific technical parameters (within standard ranges) to meet your project requirements.
