Description
Motors up to and including frame size 256T are certified for Class I, Division 1, Groups C and D (gases and vapors) and Class II, Groups E, F and G (combustible dust) with temperature codes T2D/T3B. From frame size 284T the certification covers Class I, Division 1, Group D and Class II, Groups E, F and G with the same codes. The inverter duty class winding wire withstands voltage pulses up to 2200 V, so the motors can be fed from a VFD within the stated control range. The series includes versions with a C-Face flange and in a round body for pumps and gearboxes. The motors are also used at oil and gas production sites, in paint shops, at grain elevators and flour mills. They are part of the stock program in the USA and are supplied from stock.
How to choose
The main thing when choosing is the explosion group and frame size. Up to 256T the certification covers groups C and D, and from 284T only group D, so for group C gases motors of frame size up to 256T are taken. If the area is Division 2 and an explosion-proof enclosure is not needed, look at the MAX-E1 or MAX-E2/841. When supplying from a VFD, note that the winding is rated for peaks up to 2200 V.
