Technical information

With the 3F3A-112MA-4B3, Felstrom provides a robust universal IE3 motor at an affordable price. The 3F3A-112MA-4B3 is a versatile and well-equipped 4-pole 4kW electric motor in B3 design. Like all of Felstrom’s other motors, the 3F3A-112MA-4B3 is finished with a durable RAL 7030 powder coating and has a stainless steel ID plate for optimal durability.

Felstrom motors are characterised by a good-quality seal at the D ends. Our motors are equipped with 3 PTCs as standard. And in order to guarantee a perfect installation, the terminal box can be easily turned.

Felstrom’s electric motors are available from our resellers in all regular designs such as B3, B5, B14, B34 and B35. Felstrom’s aluminium motors are provided with a convenient multi-mount system. By changing the position of the feet, the terminal box can be repositioned very easily. As such, the feet can be removed to use a B34 as a B14, or a B35 as a B5. This makes it easy to supply at an affordable price.
