1) Optimized design with MCCB size Save the cost of labor and material
2) To measure current, it is a product that converts large current into small current. More than 20,000 units are being sold annually in Vietnam and Japan.
It is designed in three phases rather than single phase-oriented competitors, so installation time is short, and the size is optimized, so space is easy to use.
