Resistor braking 251
P
brcont
Maximum continuous braking power. The braking is considered continuous if the
braking time exceeds 30 seconds.
R
min
The minimum allowed resistance value of the brake resistor
R Resistance value for the listed resistor assembly
E
R
Short energy pulse that the resistor assembly withstands every 400 seconds
P
Rcont
Continuous power (heat) dissipation of the resistor when placed correctly
The rating apply at an ambient temperature of 40 °C (104 °F)
Degree of protection and thermal constant of the resistors
Terminals and cable lead-through data
