XJZ1 series auto-transformer starting control box is suitable for 50Hz AC, rated voltage 380V, rated output power of 300kW and below three-phase squirrel cage induction motor, for non-frequent reduced-voltage starting, using the characteristics of auto-transformer voltage reduction to reduce starting current, so as to reduce the impact of motor starting on the power network.
This manual describes the XJZ1 series self‑auto‑reduction start control box, which is intended for three‑phase squirrel‑cage induction motors up to 300 kW, 380 V, 50 Hz. It outlines the applicable standards, operating limits, and protective functions such as overload, phase‑loss, and short‑circuit protection.
The document includes technical parameters for each model size, structural features, dimensions, installation guidelines, and ordering requirements, helping users select the correct model and configure the control box for reliable operation. This manual is written in Chinese.
