Product Description

Product Description

PRODUCT   INTRODUCTION

LUGAO is a leading supplier of vacuum circuit breakers. This series of vacuum circuit breakers is designed for applications that are frequently operated at rated working current or prone to multiple short-circuit breaking currents. The operating mechanism and circuit breaker body are integrated into a design with a reasonable, beautiful and compact layout. The vertical insulating shell can effectively resist impacts under various weather conditions and effectively prevent the vacuum circuit breaker from being damaged by external factors. There are two installation methods, fixed and withdrawable, to meet different usage requirements.With advanced technology and rugged design, LUGAO ensures that high-voltage circuit breakers have unparalleled reliability and performance.
