Product Description

Our circuit breakers are crafted with precision, featuring pure spring operating mechanisms that ensure a simplified and elegant structure. This design choice not only simplifies the structure but also enhances the reliability significantly. With mechanical endurance boasting over 10,000 operations, these breakers are engineered for convenience in maintenance and meet the stringent requirements for being oil-free and air-free. The use of self-energy arc-extinguishingprinciples plays a crucial role in reducing the operation power of the mechanism, thereby enhancing the product's operational reliability.

Our flanges are meticulously designed with a dual-seal structural concept. The outer seal ring ensures water-proofing while the inner seal ring offers gas proofing. This dual-seal design significantly reduces potential leakage, making it an ideal choice for outdoor operations.
