P Maximum continuous braking power. The braking is considered continuous if the braking time
brcont
exceeds 30 seconds.
R The minimum allowed resistance value of the brake resistor
min
R Resistance value for the listed resistor assembly
E Short energy pulse that the resistor assembly withstands every 400 seconds
R
P Continuous power (heat) dissipation of the resistor when placed correctly
Rcont
The ratings apply at an ambient temperature of 40 °C (104 °F)
