Electric motor 200 kW, 1490 rpm, 400 V / 690 V, 4LC-315L2-4 LV

When selecting a drive for production modernisation, it is worth focusing on operating efficiency, voltage ratios and mechanical reserve. The 4LC-315L2-4 model with an output of 200 kW and a supply of 400 V / 690 V belongs to the speed class of 1400-1500 rpm, which makes it ideal for stable operation in lines with long-term load. Thanks to IE4 efficiency class, it can reduce energy losses by approximately 15 % to 20 % compared with IE3, which in continuous operation translates into noticeable savings and a lower load on distribution systems. This three-phase motor from VYBO Electric is suitable where super premium efficiency, reliable starting and precisely controlled integration into existing technology are important.

Construction with reserve for long-term load

For plants that are replacing an older drive, it is important not only to consider the nominal value, but also the motor behaviour during starting and process fluctuations. The rated current in delta 400 V connection reaches 339 A and in star 690 V connection 197 A, which makes power supply design easier in low-voltage infrastructure. The starting ratio Tst/Tn 1.8 and breakdown ratio Tmax/Tn 2.2 show that the motor is ready for robust starting and for operation in technological units with higher mechanical inertia. The starting current ratio Ist/In 8.5 is a value that industrial designers commonly work with when setting protection and distribution coordination.

The all-cast-iron design with IEC frame 315 mm provides high assembly strength and better vibration damping during long-term use. Noise level 88 dB(A) corresponds to a power class intended for heavier applications and, when installed correctly, supports stable operation of the entire technology. Rotor inertia 5.4 kg*m² helps with a balanced start of the drive, which is especially appreciated by technology suppliers when designing entire lines. Bearings 6319-C3 on both the DE and NDE sides increase operational reliability under higher load, and the 3 PTC thermistors provide a protective input for monitoring winding temperature.

Speed range 1400-1500 rpm for stable industrial performance

In this segment, it is important for the motor to maintain nominal speed without unnecessary fluctuations while also delivering energy-efficient operation. Efficiency of 96.7 % and power factor of 0.9 create good conditions for economical deployment in applications with high running time. In practice, this means lower heat losses, reduced cooling requirements and a better operating cost balance during long-term utilisation. The 2-M63X1.5 cable glands make installation easier and help route supply cables properly in space-restricted assemblies.

Parameters suitable for drive design

• Nominal speed of 1490 rpm supports stable operation in standard industrial use.
• Output of 200 kW provides the necessary reserve for pumps, fans and other medium-duty to heavy-duty drives.
• Supply of 400 V / 690 V simplifies integration into common low-voltage systems.
• Packed weight of 1214 kg indicates robust construction suitable for demanding use.
• Pack dimensions of 1412*727*1026 mm should be taken into account during handling, storage and installation planning.
• Current values of 339 A at delta 400 V and 197 A at star 690 V are important for the design of protection and distribution systems.
• Ratios Tst/Tn 1.8 and Tmax/Tn 2.2 help estimate starting behaviour under load.
• The 3 PTC thermistors support temperature monitoring in operations with higher safety requirements.

Use in universal industrial operations

This power class is well suited to pump stations, fan assemblies, conveyors, mixers, compressor technology, extrusion lines, bulk material processing and other universal industrial applications where a reliable and efficient drive is required. Thanks to the combination of higher efficiency, robust construction and the option of connection to both 400 V and 690 V networks, the motor is suitable for manufacturing plants, technology suppliers and businesses modernising existing drive assemblies without major intervention in the infrastructure.

VYBO Electric builds on its own research and development, which is reflected in technical support when selecting the right drive and aligning it with real-world operation. If you need a motor for a new installation or a replacement for an older unit, check the suitability of the motor for your application and verify its compliance with the required duty type, starting conditions and available installation space.
