Maximum continuous braking power. The braking is considered continuous if the braking
time exceeds 30 seconds.
P
brcont
The minimum permitted resistance value of the brake resistor
R
min
Resistance value for the listed resistor assembly
R
Short energy pulse that the resistor assembly withstands every 400 seconds
E
R
Continuous power (heat) dissipation of the resistor when placed correctly
