Crompton Greaves (CEG) – other models: the collective page of MEPS-registered three-phase motors from the Indian manufacturer outside the named ranges, frame sizes 80 to 160, 0.75 to 18.5 kW, 2- to 8-pole
This page brings together the three-phase motors from Crompton Greaves that the Australian energy-efficiency register (GEMS/MEPS) does not assign to a named series. Crompton Greaves is an Indian electrical engineering manufacturer whose motor production traces back to the former Indian operation of Crompton Parkinson and today trades as CG Power and Industrial Solutions. Type designations such as G CA112M 28 2 or G DA100L 28 4 follow a modular scheme of series code (CA/DA), frame size and frame length plus a two-digit code, followed by the pole count at the end.

The register lists here 39 versions with 0.75 to 18.5 kW, two- to eight-pole, at supply voltages of 400 to 415 V. Efficiency at full load ranges from 75.11 to 91.7%, and at 75% load from 73.04 to 91.8%. Frame sizes run from 80 to 160, manufactured in India. Mounting covers a wide spectrum from B3 through B34, B35, B5 to B8 as well as the vertical forms V1, V3, V15, V18, V19 and V36; testing followed AS/NZS 1359.5:2004 using test method B, and none of the motors reaches a High Efficiency classification under GEMS.
The page thus shows the compact power segment up to 18.5 kW with which Crompton Greaves competes in the Indian and Australia-Pacific markets against other suppliers of standardised IEC motors; the broad range of mounting codes covers foot, flange and vertical mounting for varied applications in industry and building services.
When buying used, check the condition of the rolling bearings, a checked winding insulation resistance, corrosion marks on the housing, and a legible nameplate showing frame size, pole count and mounting code, since the wide variety of codes makes mix-ups easy when buying spares. The terminal box and fan cover should be checked for cracks and loose fasteners; spares generally run through the CG sales network.

Frequently asked questions
How much power does the Ceg/crompton Greaves G CA112M 28 4 have?
The Ceg/crompton Greaves G CA112M 28 4 delivers 4 kW.
What to check before buying
- Match the data plate against the order: frame size, mounting and rating have to agree.
- Check the ingress rating against the installation site — outdoors or in dust the demands differ.
- Hold the mounting form and dimensions against the existing seat before ordering.
- The pole count sets the speed — when replacing an older unit, compare this first.
- For used units, ask about winding condition and bearing play.
- Ask about parts availability for this series — the running costs hang on it.
