Product

DGB7-125

DGB7-125 miniature case circuit breaker is used in AC 50/60 line with rated voltage 230V (for 1P) or 400V (for 2P/3P/4P) and rated current up to 125A for overload and short-circuit protection. It can also be used for infrequent ON/OFF switching of the line under the normal operation. The circuit breaker is characterized by artistic shape, small size, light weight, excellent and reliable performance, high breaking capacity, quick tripping, and rail-mounted installation
