Description
The ceramic resistor model SPLC-WR-50-1200 is most frequently used as a brake resistor for a frequency converter 11 kW for three-phase motors 380 V — when choosing, refer to the frequency converter manufacturer's recommended resistor characteristics and calculated braking power of the motor. This wire-wound resistor has a resistance of 50 Ohm and a capacity of 1200 W.
WR series brake resistors are made with a ceramic tube wrapped with wire of iron-chromium-aluminium alloy (by default) or nichrome (upon request). The ceramic body acts as an insulator and heat sink, resistant to high temperatures and corrosion. The wire has high specific electrical conductivity, allowing effective heat dissipation generated during motor braking.
