The M3GP 100LB 2 from ABB is a three-phase induction motor. The rated output is 3 kW. The motor is two-pole, which at 50 Hz gives a synchronous speed of 3,000 rpm. The rated voltage is 415 V. The housing is frame size 100. The protection class is IP55, IP56, IP65 and IP66. The efficiency is 86.3 per cent at full load, 86.6 per cent at 75 per cent load and 85 per cent at half load. Stated countries of manufacture: Finland and Poland. The data is based on the Australian MEPS registration under the GEMS Determination 2012; measured to IEC 60034-2-1 (Edition 2.0). Rated output across the ABB range ranges from 0.75 to 185 kW; the M3GP 100LB 2 sits at the bottom of that range with 3 kW. Its immediate neighbours are the M3MA 90 MB 2 below it with 2.2 kW and the M2BA 112 MB 4B above it with 4 kW. 2143 ABB models across 2 series are on record. The model is listed under Electric motors. 22 verified figures from 1 source are on file.

ABB M3GP – non-sparking cast-iron motors for zones 2 and 22 (Ex nA/Ex ec, Ex t): frame sizes 80 to 355, 0.75 to 185 kW

M3GP is the Ex version of ABB's cast-iron motor for hazardous areas where a gas atmosphere is unlikely: zone 2 (gas) and zone 22 (dust). The protection type is called 'non-sparking' in the standard – formerly Ex nA, since IEC 60079-7:2015 Ex ec – or Ex t for protection by enclosure against combustible dust. Unlike the flameproof M3JP, an ignition is not contained but prevented by design: no sparks or hot surfaces arise in normal operation. That makes the M3GP the standard for refineries, tank farms, chemical plants and mills outside zone 1.

The type code follows the series pattern: M3 for motor and generation, G for the cast-iron frame in Ex execution, P for process performance, then frame size, frame length and number of poles. The register holds 262 versions from frame size 80 to 355 with 0.75 to 185 kW, two- to eight-pole; full-load efficiencies run from 74.1 to 97.2 %, protection from IP55 to IP66. Rated voltages of 415 to 690 V are recorded – most registrations name Finland and Poland as manufacturing locations.

The technical data match the M3BP because the Ex version is built on the same active part; in addition, temperature class (usually T3), gas group (IIA to IIC) and the type-examination certificate under ATEX or IECEx are stated on the rating plate.

When replacing: protection type, zone and temperature class must match the installation, inverter duty needs an explicit approval, and repairs may only be carried out by certified Ex workshops.

Frequently asked questions

How much power does the ABB M3GP 100LB 2 have?

The ABB M3GP 100LB 2 delivers 3 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.
