1) For the Performance Line, motor protection by means of PTC thermistors
with 3 built-in temperature sensors for tripping (motor protection code letter
B) is already included in the basic price. For the Performance Line, the
option "without motor protection" (motor protection code letter A) is not
possible.
2) Evaluation with associated tripping unit (see Catalog IC 10) is recommended.
3) Motors in these frame sizes have a second rating plate (T1/T2 and T3) as
standard.
The T3 power is stamped on the rating plate as standard if the following
motors are selected with PTC thermistor (protection by PTC thermistor
only) or voltage code "90":
– 2-pole motors: Frame sizes 132 to 160
– 4-pole motors: Frame size 180
Alternatively, with order code B33, the "T1/T2 power is stamped on the
rating plate".
