结构特点 Structural features

QCX5 系列磁力起动器以喷塑铁壳为外壳，外壳美观，外壳坚固，封闭，能适应户外较恶劣的工作环境。起动器带断相保护功能，能防止电动机因断相造
成单相运转而损坏的事故发生。
本公司生产的 QCX5 系列磁力起动器广泛应用于空气压综机制造业。
The QCX5 series magnetic starter is made of spray-coated iron shell. The shell is beautiful, the shell is firm and closed, and it can adapt to the
harsh outdoor working environment. The starter has a phase-break protection function that prevents accidents in which the motor is damaged
by single-phase operation due to phase failure.
The QCX5 series magnetic starters produced by our company are widely used in the air compressor manufacturing industry.
