Description
The ceramic resistor model SPLC-WR-150-500 is most commonly used as a brake resistor for frequency converter 5.5 kW for three-phase motors 380 V — when choosing, rely on the manufacturer's recommended inverter characteristics and calculated engine braking power. This wire wound resistor has a resistance of 500 W and power of 150 Ohm.
Brake resistors of the WR series are made from a ceramic tube, over which is wound iron-chromium-aluminium alloy wire (by default) or nichrome (on request). The ceramic body serves as an insulator and heat dissipator, resistant to high temperatures and corrosion. The wire has high specific electrical conductivity, allowing efficient heat dissipation generated during motor braking.
