Product Description
PKM1 3P AC MCCB series is a new type product developed and manufactured by Adopting international advanced technology. It is supplied with rated insulation voltage 800V and used for circuit of AC 50Hz, rated operation voltage AC 400V or below rated operation current up to 1600A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current, short circuit and under voltage, the product is capable of preventing damage of circuits and supply units.
The mccb can be sorted to L type (standard),M type (high breaking), H type(higher breaking) according to its rated limit short circuit breaking capacity.
The mccb has the features small volume, breaking capacity high, electric arcing short ,anti-vibration. It is the ideal product for application in land and ship.
The installation can be vertical or level and the standard conforms to IEC60947-2 and GB14048.2
