AMDG-X/E621 series motor protection is a motor protection device with DSP as the core, which has functions of phase loss, short circuit, grounding, stalling, overload, unbalanced current and underload. It is suitable for three-phase AC motors with a voltage not exceeding 1140V and a frequency of 50Hz or 60Hz.
The AMDG‑X/E621 series motor protector from XWAM provides comprehensive protection for three‑phase AC motors up to 1140 V and 50/60 Hz. It uses a DSP core, digital settings and a 5‑digit LED display to show motor currents, parameters and fault codes.
The manual describes operation, parameter configuration, fault codes, wiring diagrams and PLC/DCS communication, as well as installation dimensions and mounting instructions. This manual is written in Chinese.
