Corrosion class C3 medium

Stator winding Material Copper Insulation Insulation class F. Temperature rise class B unless otherwise stated.

Totally enclosed fan cooled IP 55, IP56 or IP65. Special designed high sealed cable gland used at the cable entrance; there are two terminations for earthing, one at the terminal box internal and another one at the outside of the frame, to ensure the electric security throughly. High rigidity cast iron material to strengthen the resistance of mechanical impacting. As standard, terminal boxes are mounted at the top. Left side, right side are on request.Generally, Terminal box can turn 4 x 90°, very conveniently for use.

Reliable windings To ensure long lifetime, the winding is made from the latest available material in class F protection and temperature rise 95K according to the classification societies' rules. If lower temperature rise, i.e. class B (70K) is needed, it is necessary to reduce the output range. As an indication the following formula can be used.

Balancing method Half key balancing as standard

Drain holes Drain holes with closable plastic plugs, open on delivery

Enclosure IP 55 Higher protection on request

Cooling method IC 411

Lifting lugs Integrated cast iron lifting lugs.
