Benefit

Maximum Energy on lowest space.This REO-Braking Resistor is very compact at high power. The resistors aredesigned for a power on time up to max. 5%. Smaller duty cycles must bedesigned by customer specifications.Versions up to IP 65. High - impedance on failure.

Optional:> Temperature switch> Protection against accidental contact against high surface temperatures

Maximum surface temperature

<h4>Note: Permanent over-temperatures of > 200 K may impair protectionrating.</h4>The ratings apply for 100 % duty cycle and free access and exit of cooling air.In general: Is the ambient temperature higher than 40 °C, the continuous powermust be reduced by 5 % per 10 K temperature rise.
