4KTC Motors for hazardous areas - EEx d and EEx de
Explosion-protected electric motors are used in industrial plants with a potentiall explosive atmosphere containing inflamable fumes (i.e. chemical industry, oil refineries).
These are three-phase asynchronous electric motors with shot-circuit rotor, according to the CENELEC EN 50014, EN 50018, EN 50019 (IEC 79-0, IEC 79-1).
All 4KTC motors are manufactured in accordance with IEC 34-1/9.
The bearings are maintenance free lubricated with lithium-based grease.
Motors are fitted with V-seals.
Mounting is availiable in B3, B5, B14S, B14L B35, B34S, B34L.
