Standard asynchronous three-phase electric motor with short-circuited squirrel-cage rotor for general purposes in industrial applications; enclosed, externally fan-cooled (with IC 411 cooling method), thermal insulation class F (class B motor overtemperature class with standard power; class B or B/F for the remaining three-phase and single-phase motors).
Motor designed for continuous duty (S1) at rated voltage and frequency. Ambient air temperature: –15 to +40°C. Maximum altitude: 1000 m above sea level. Supply at nominal voltage 400 [V] ±5% and nominal frequency 50 [Hz] ±2%. Motors CHT-A, CHT-G and CHT-M are not suitable for use in places where there is a risk of explosion.
