ABB lists the M3JP 280MLA 4 as a three-phase induction motor. The rated output is 132 kW. The motor is four-pole, which at 50 Hz gives a synchronous speed of 1,500 rpm. The housing is frame size 280. The protection class is IP55, IP56 and IP65. The efficiency is 95.4 per cent at full load, 95.6 per cent at 75 per cent load and 95.3 per cent at half load. Mounting arrangements to IEC 60034-7: B3, B5, B8, B35, V1, V3, V5 and V6. Stated countries of manufacture: Finland, China and Poland. The figures come from the Australian MEPS register 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 M3JP 280MLA 4 sits in the upper part of that range with 132 kW. Its immediate neighbours are the M3KP315SMC6 below it with 110 kW and the M2BA 355SMA6 above it with 150 kW. 2143 ABB models across 2 series are on record. The model is listed under Electric motors. 24 verified figures from 1 source are on file.

ABB M3JP – flameproof motors (Ex d) for zone 1: cast-iron frame, frame sizes 80 to 355, 0.75 to 185 kW

M3JP is ABB's flameproof motor for zones 1 and 2 – areas where an explosive gas atmosphere is to be expected in normal operation. The protection type Ex d (Ex db under the newer standard) rests on a principle from mining: the enclosure is so strong, and the gaps at shaft and end shields so narrow and long, that an ignition inside is withstood and the flame cannot propagate outward. The letter J in the type code marks exactly this flameproof execution with a cast-iron frame at ABB; the sister type M3KP adds a terminal box in increased safety (Ex de).

The rest of the type code follows the process motor: IEC frame size, frame length (S, M, L), number of poles, plus H or L for the winding variant. The register holds 197 versions from frame size 80 to 355, 0.75 to 185 kW, two- to eight-pole, with full-load efficiencies from 75.3 to 97.2 % and protection from IP55 to IP66; rated voltages are recorded as 415 to 690 V, manufacturing locations mainly Finland, Poland, India and China.

The figures largely match the M3BP because the active part is the same – the difference lies in the enclosure, which is heavier and more expensive and whose flame paths must not be damaged during maintenance. Certification under ATEX and IECEx states gas group (IIB or IIC) and temperature class.

When buying: Ex d motors may only be operated with certified accessories (cable glands, terminal box), inverter duty needs an explicit release, and any repair to the enclosure requires a certified Ex workshop.

Frequently asked questions

How much power does the ABB M3JP 280MLA 4 have?

The ABB M3JP 280MLA 4 delivers 132 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.
