QC系列磁力起动箱适用于船舶50Hz或60Hz电网，用来就地控制或遥控三相异步电动机的起步／停止和运转方式，并对电动机实施短路、过载、断相以及失压保护。起动方式根据电动机功率的递增般分为直接起动、星／三角起动、自耦
式和落地柜式，防护等级根据安裝场所的不同可以达到P22或P44
QC series magnetic starters box are applicable to ship mains SOHZ or 60HZ. They are used to locally control or remotely control the start/stop and running mode, and implement the protection e.g.short-circuit, overload, phase-break and under- voltage for the 3-phase asynchronous motor. The starting forms are dipartite as per increased motor power capacity ,such as direct-on-line start, Y/astart, autotransformer start and frequency converted start. The running mode can be divided into unidirectional, reversible and double-speed running. Based upon the different capacity, they can be built wll-mounted or floor-mounted. The protective degree of the enclosure can be of IP22 or IP44 according to its respective installation area.
