Braking resistors type BW... / BW...-T / BW...-P
Technical Data and Dimension Drawings
Parallel
connection
Two braking resistors with the same value must be connected in parallel for some
inverter/resistor combinations. In this case, the trip current must be set on the bimetallic
relay to twice the value of I
F
entered in the table. For the BW...-T / BW...-P braking
resistors, the temperature switch / overcurrent relay must be connected in series.
