GLOQ1B-T Automatic Transfer Switching
  • Product Overview

 

 

GLOQ1B-T type product is a new generation of PC switches adopting coil instant operation. Compared with the traditional switch which adopts motor drive for conversion,it has the advantages of simple structure, fast conversion speed (time<80ms) and so on.In addition, the main contact system is a SPDT (V-type) structure, which will not connect with two powers at the same time even in the emergent situation.

Application range

The rated insulation voltage of the product is 690V, the rated frequency is 50/60Hz,the rated voltage is 400VAC and the rated current is 160A-400A. The product is mainly used for the conversion of emergency power supply system between two powers so as to ensure the important load (for example, firefighting load) can continuously and reliably operate. Mainly used for the nationally specified first-grade current, the product is applicable to the occasions requiring continuous normal power supply such as highrise building, post and firefighting, coalmine and shipping, chemical metallurgy, industrial production line, medical sanitation, military facilities, etc.
