I. usage
QBZ Series Mining Flameproof Vacuum Electromagnetic Starter is suitable for starting or stopping of mine flameproof three-phase squirrel cage asynchronous motor with explosive gas mixture (methane) and coal dust in underground coal mine or industrial and mining enterprises. It is used in power system with 50Hz AC and 1140V voltage, and can be used to control the starting or stopping of mine flameproof three-phase squirrel cage asynchronous motor locally or remotely. It can commutate when the parallel control motor is out of power, and protect the motor and related circuit at the same time. This series of starters are especially suitable for frequent operation and heavy load of coal mine machinery and equipment, and also for industrial and mining enterprises with the same type of explosive gas mixture.
Two, function
1. Starter has overload, short circuit, phase break and leakage blocking protection.
2. The rated current can be adjusted by dialing and gear setting.
