All braking resistors feature a temperature switch for protection
against thermal overload.
This dry contact (N/C) can be directly integrated into the DA1
variable frequency drive’s control section and work as an
external fault message (control terminal 10, DI5, parameter
P9-08 = 5).
Exception:
Resistors DX-BR3-100 and DX-BR5-33 do not feature a circuit-
breaker. They are inserted into the corresponding recesses on
the DA1 variable frequency drive’s heat sinks (frame sizes FS2
and FS3 for IP20 and FS4 and FS5 for IP55) and are
automatically protected against thermal overloads as a result
(heat sink overtemperature, display:
O- t
).
