Features of VCB Tulip Type Contacts
Performance Enhancements: The tulip type design provides superior performance with significantly reduced loop resistance and lower temperature rise. This leads to more efficient and reliable operation.
Durability and Longevity: These tulip contacts offer extended durability and a longer service life compared to traditional contacts. They also feature enhanced antioxidant capabilities.
Improved Usability and Reliability: The plug-in and plug-out force is notably reduced, making for smoother and easier operation. The design ensures a stable connection with a consistent contact force and resistance, preventing false contacts and floating issues.
Material and Construction: The contacts are made with imported non-magnetic stainless steel to prevent eddy currents. The contact piece, stamped from T2 copper, has a thick silver plating applied with a brush for strong abrasion resistance. A tarnish-resistant treatment prevents discoloration, oxidation, and shedding of the silver layer. The precise fixed contact insertion depth is standardized for optimal performance.
