QC系列磁力起動箱適用于船舶50Hz或60Hz電網，用來就地控制或遙控三相異步電動機的起步／停止和運轉方式，并對電動機實施短路、過載、斷相以及失壓保護。起動方式根據電動機功率的遞增般分為直接起動、星／三角起動、自耦
式和落地柜式，防護等級根據安裝場所的不同可以達到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.
