Maximum continuous braking power. The braking is considered continuous if the braking time exceeds
30 seconds. P
brcont
The minimum allowed 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 P
Rrcont
The ratings apply at an ambient temperature of 40 °C (104 °F).
￭ SAFUR resistors
The degree of protection of SAFUR resistors is IP00. The resistors are not UL listed. The
thermal time constant of the resistors is 555 seconds.
