Indoor Medium Voltage SF6 Circuit Breaker 12kV 40.5kV

Product Introduction
The FEP Indoor SF6 Circuit Breaker is the latest generation of high-voltage switching equipment developed based on mature and reliable SF6 interruption technology. It fully complies with international standards including DL and IEC, making it a reliable choice for global medium and high-voltage power distribution projects.Designed for seamless compatibility, this SF6 circuit breaker is interchangeable when matched with AMS switchgear and can be easily and reliably integrated with most mainstream switchgear available on the global market. It is widely used as a core switching component in indoor high-voltage power systems, delivering stable performance and strong adaptability.

Core Advantages & Technical Highlights

• Mature SF6 Interruption Technology: Adopts proven SF6 arc-extinguishing technology, ensuring fast, clean and reliable arc extinction, long electrical life, and low maintenance requirements, which is widely recognized in the global high-voltage equipment industry.
• Global Standard Compliance: Fully meets the requirements of international standards such as DL and IEC, ensuring consistent performance with global power system specifications and facilitating project acceptance for overseas purchasers.
•  Excellent Switchgear Compatibility: Standardized structural design allows easy, flexible and safe installation in mainstream switchgear from major manufacturers worldwide. It is interchangeable when matched with AMS switchgear, reducing replacement and upgrade costs.
• High Safety Performance: The internal arc-extinguishing chamber operates under low air pressure. Even if the internal pressure rises due to gas compression and heat increase during operation, it remains in a low-pressure gas state, eliminating potential safety hazards and ensuring operational safety.
• Easy Installation & Operation: Optimized structural design simplifies on-site installation and debugging, requiring no complex tools or professional skills, which saves time and labor costs for project construction.
