630A 24KV Flip Type ANSI Load Break Switch
The 24kV 630A Single Phase Oil Immersed Loadbreak Switch is a specialized switching device developed for medium-voltage oil-filled transformer applications. It enables safe switching and sectionalizing of electrical loads while maintaining stable insulation performance inside transformer oil environments.
Key Feature
Over the past 20 years of production experience in loadbreak switches, Wenzhou Best company's contact system of the switch adopts a double-bridge floating contacts type. The moving and static contacts have excellent contact performance, with low resistance and strong current-carrying capacity. All these contact are made of T2 copper equivalent to C1100 copper.
Housing are made of Germany BASF PBT.

Advantages For Transformer Manufacturers
Compact Structural Design
Wenzhou Best's loadbreak switch's center shaft and housing are compression-molded using raw materials from BASF Germany; This high-performance center shaft and housing assembly effectively prevents the electric arcs generated during contact from breaking down the housing. Improved arc interruption stability.

Lower Maintenance Requirements
Oil insulation helps protect switching contacts and reduces wear caused by repeated operations.
Installation Notes
- Intended for use inside qualified oil-filled transformer tanks
- Ensure correct insulation oil level before commissioning
- Installation should be performed by trained electrical personnel
- Routine inspection of the operating mechanism is recommended
