General
HGCK series switchgear comprises power distribution central cabinet(PC) and motor control central cabinet(MCC). Suitable for distribution system of AC 50Hzf max working voltage up to 660V, max working current 3150A in the power plant, transformer substation, industrial and mining enterprise, etc., it is used to convert, distribution and control the electric energy of power motor control or lighting distributing equipment. With advantages like high breaking ability, superior dynamic and thermal stability, advanced and reasonable structure, practicable electric scheme, powerful serial property and versatility, available random combination of kinds of scheme unit, nice appearance, high protection level, safety and reliability and convenience of maintenance, the product else can save the space by reason that one cabinet can contain so many circuits. It is in line with the standards IEC439, GB7251-87 Low-voltage Switchgear Assembly and ZBK36001-89 Low-voltage Draw-out Switchgear Assembly.
