Description
The ceramic resistor model SPLC-WR-400-150 is most commonly used as a braking resistor for a 1.5 kW frequency converter for three-phase motors 380 V – when choosing, rely on the manufacturer's recommended characteristics of the frequency converter and the calculated braking power of the motor. This wire-wound resistor has a resistance of 400 Ohm and power of 150 W.
The WR series braking resistors are made of a ceramic tube, on which wire of iron-chromium-aluminium alloy (by default) or nichrome (on request) is wound. The ceramic body acts as an insulator and heat sink, resistant to high temperatures and corrosion. The wire has high electrical conductivity, allowing efficient dissipation of the heat generated when braking the electric motor.
