Q&A
Do you support OEM and customized specifications?
Yes. As a source manufacturer, we provide OEM branding, customized current ratings, packaging design, and technical solutions based on your project requirements.
Can this current transformer be used for both energy metering and relay protection?
No. One current transformer should be used either for energy metering or for relay protection, not both at the same time, to ensure measurement accuracy.
Are your products suitable for international markets?
Yes, our products are widely exported to over 20+ countries and regions, including:
- Europe
- North America
- Middle East
- Southeast Asia
All products are designed to comply with international electrical standards and project requirements, making them suitable for global distribution and engineering applications.
What is an automatic reclosing circuit breaker?
