Description:
A high-power, three-phase asynchronous motor with a cast iron frame, offering IE3 efficiency. The motor is rated for continuous duty (S1) and features an IP55 enclosure and TEFC cooling (IC 411). A key feature is its certification for Zone 22 hazardous locations (CE II 3D Ex tc IIIB T125°C Dc). It includes 3xPTC thermistors for thermal protection. The mounting configuration is B35 (foot and flange). The motor is designed for demanding industrial applications such as compressors, large fans, and crushers, particularly where combustible dusts may be present.
