AC metal enclosed switchgear, is suitable for three-phase three wire, three-phase four-wire, and three-phase five-wire systems with AC voltage of 500V and below in power generation and industrial and mining enterprises, used for power lighting distribution. Low-voltage power cabinet is characterized by flexible distribution scheme, being convenient for combination, strong practicality, and novel structure.
Main structural features
- The main electrical performance fully complies with IEC60439.1 and GB7251.12
- The auxiliary circuit has the functions of local, remote, automatic control, and switching between local control and remote control, and the contactor can collect DC hold.
- The main receiving switch may choose instantaneous trip protection. In order to cooperate with the switches of next level, the instantaneous protection is cancelled to avoid overstep tripping, and it also has functions of self-switching, manual operation, and automatic switching.
- The main switch of the feeding circuit has instantaneous trip and thermal magnetic trip protection, and leakage protection can be added when requested by the user.
- The motor control circuit has short-circuit instantaneous, overload, under-voltage release and phase failure protection.
- The receiving circuit is equipped with an ammeter and a voltmeter.
