Description
The ceramic resistor model SPLC-WR-750-100 is most commonly used as a brake resistor for 0.75 kW drive for three-phase motors 380 V — when selecting, rely on the characteristics recommended by the frequency converter manufacturer and the calculated braking power of the motor. This wire wound resistor has a resistance of 400 Ohm and a power rating of 100 W.
Brake resistors of the WR series are made from a ceramic tube wound with wire made of an iron-chromium-aluminium alloy (by default) or nichrome (on order). The ceramic body serves as an insulator and heat sink, resistant to high temperatures and corrosion. The wire has high specific electrical conductivity, allowing effective dissipation of the heat generated during motor braking.
