ALPHA
CCR BT is our range of compact Aluminum Profile Brake
Resistors with protection class IP65. The resistor is
mounted with a connection box, which contains cable glands
and cable connection to the resistor.
 The
resistors are supplied with an internal 200°C thermostat.
The
CCR BT resistors have a "High Temperature" warning
label on the connector box and are optionally supplied
with a Protecting Grating (PG).
The
mounting brackets are equipped with thermal expansion
compensation.

 Pulse
Load
The
curves show the pulse load ability compared to the nominal
load for the CCR resistors under the following conditions:
The load is a periodic pulse load with a constant period
time of 120 sec and a pulse width from one second to
40 sec.
For
all other load conditions please contact DANOTHERM.
By mean of individual thermal models we can simulate
the rises of temperatures in the components and on the
surfaces during and between the pulses.
