SGB-63N Series Miniature Circuit Breaker

Much higher short circuit breaking capacity, Dual-connection convenient for both standard busbar and conductor connection. Improved safety • of operators offered by special design from terminals. Much longer service life thanks to energy-storage operating mechanism.Enclosure • and functional parts made from imported plastics with flame-retardant, heat-resistant, and impulse-proof properties. Higher current-limiting • capacity ensuring a cost-effective range of products. Different handle color for different rated current with contactor condition indicator.
