Description
The ceramic resistor model SPLC-WR-400-200 is commonly used as a braking resistor for a 1.5 kW frequency converter for three-phase motors 380 V — selection should be based on the recommended characteristics provided by the frequency converter manufacturer and calculated motor braking power. This wire-wound resistor has a resistance of 400 Ohm and a power rating of 200 Watt.
WR series braking resistors are made from a ceramic tube wound with a wire of iron-chromium-aluminium alloy (by default) or nichrome (on request). The ceramic body serves as an insulator and heatsink, resistant to high temperatures and corrosion. The wire has high specific electrical conductivity, allowing efficient dissipation of heat generated during motor braking.
