Products
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.
