EBS9MH series is type moulded case circuit breaker that developed and manufactured by???adopting international MCCB advantages and market requirements. It is supplied with rated insulating voltage 800V, and use in the distribution network circuit of AC 50/60Hz, rated?operating voltage AC690V, rated operating current up to 1250A. It could allot electric?energy and?protect circuit &electric power unit?against?over-load,?short-circuit,?under-volt-?age etc.?It also protects motor frequently start&over-load,?short-circuit,?under-voltage.
This?MCCB features?by small size,?high?breaking capacity, and short flashover etc.?installed?vertically or horizontally.?It?is convenient &?ideal?product for?user.
This?product conforms to?IEC60974-2 standard.
(1)Miniaturized?Design
125A frame?level size?is same to?100A,?it can?meet specifically?requirements for?installation size.
(2)Unified Size
At the same frame level, the?installation size?is same?at?different?breaking?capacity?(C,?S,?M,?H) and different functions (ACB,?RCCB, Thermal-magneticadjustable type).
(3)Reasonable?Parameters Setting
It provides the setting of over-load & long time delay inverse time limit, short circuit & instanta-neous operation. And users can set data based on their needs to realize?reasonable distribution.
