QJR Series Explosion-proof Soft Starters

The QJR series explosion-proof soft starters are designed for the soft-start of the three-phase asynchronous motor. The rated voltage of the motor shall be no more than 1140V with the frequency of 50Hz. The rated current can be as high as 400A. Controlled by this product, the motor with load will start up smoothly. Since the impulse of starting current on the grid and load equipment is reduced, the energy is saved accordingly.

Being explosion-proof, this soft starter is widely used in the environment with poor conditions, such as metallurgy, ports, coal mine, coal preparation plant, the places containing explosive gas like methane, and some others.
