Severe Duty – Three-Phase Motors
IEC TRU-METRIC™ - Three Phase
TEFC
This line is designed and built according
to European IEC34 and IEC79 standards.
Standard Features:
- 60 Hz (1.15 service factor) and 50 Hz (1.0
service factor)
- Class F insulation (Impregnation Resin and
Magnet wire are class H)
- F2 mounted as standard
(F1 convertible)
- Stainless Steel Nameplate - Laser etched
with high contrast background
- Regreasable ball bearings (Frames 160 and
- up)

- Class I, Div. 2, Groups A, B, C & D – T3,
Class II, Div 2, Groups F & G – T3C (Cast
Iron Frames only)
- Suitable for WYE/Delta Start (W and Y
voltage code motors)
Features that make a difference:
- 1.25 service factor for 60 Hz
operation (IE3)
- 1.15 service factor for 60 Hz
operation (IE2)
- Optimized ventilation system for
cooler operation and reduced noise
levels
- Solid base for reduced vibration
levels (Cast Iron Frames)
- Frames 225 and up can easily be F1
(B3L) converted by simply rotating
the terminal box adapter or F3 by
removing it
- Terminal blocks
Inverter Rated (IE3):
1000:1 for variable torque
12:1 for constant torque
* IE2 is 10:1 VT and 4:1 CT
