QJZ2-□/□(N)
Mine-used flameproof and intrinsically safe(Reversible) Vacuum electromagnetic starter
Purpose and scope of applicationApplication and range of application
QJZ2-series mine-used flameproof reversible vacuum electromagnetic starters (hereinafter referred to as starters) are applicable to underground coal mines where the surrounding air medium contains explosive gas mixtures(CH₄). In a three-phase AC50Hz, voltage380,660, 1140V circuit, they are used for direct starting, stopping, and forward and reverse rotation control of three-phase squirrel-cage asynchronous motors, and have protection functions such as overload, short circuit, phase loss, and leakage locking
