EcST(K,L)e… Motor with flame-proof enclosure and with increased safety terminal box.
cST(K,L)e… Motor and terminal box with flame-proof enclosure.
In standard execution main terminal box is in increased safety design (Ex eb) equipped with 3 supply terminals for DOL or VSD ("-f" execution) supply and one cable gland. On request motors can be equipped with fully flameproof main terminal box (Ex db).
Three-phase squirrel-cage explosion proof motors for chemical industry
One speed explosion-proof motors according to IEC 60079-0, IEC 60079-1 and IEC 60079-7 standard with ATEX certificate.
Motors are designed to equipment installed in rooms and areas (zone 1 or 2), in which explosive mixtures of combustible gas and vapour with air, classified as group II, temperature class T5 (maximum surface temperature below 100°C) or lower, may appear

Option: Flameproof motors with electromagnetic brake:
HEX DC electromagnetic brakes
HEX brakes
HEX brakes provide protection:
• against methane and coal dust explosion for the I group of devices, category M2 (I M2 Ex db [ia] I Mb)
• against explosion of gases for the II group of devices, category 2G (I 2G Ex db [ia] IIB T4 Gb)
• against dust explosion for the II group of devices, category 2D (II 2D Ex tb [ia] IIIC T125°C Db)
