RWST

Vishay Sfernice

Fixed Wirewound High Power Vitreous Resistors

Electrical Traction Model

FEATURES

• 95 W to 800 W at 25 °C

• NF C 93-214

• RB 25 x 168, RB 30 x 250

• Rugged construction for use in severe environmental

conditions

The RWST vitreous wirewound high power resistors are known for their excellent reliability which has developed out of the

VISHAY SFERNICE experience over several decades in the field of high current applications.

Extremely severe conditions of use are encountered in electrical traction including repeated overloads. To withstand such

conditions the new RWST model is extremely rugged and is manufactured to a very carefully monitored process using the best

materials.

NF F 16101, 10/1988 and 16102, 04/1992: Not applicable (our parts are made of metallic and refractory materials).

NF C 93-214. Performances according to NF C 93-214.
