What is the Schneider Electric VW3A7743?
This braking resistor is an option for variable speed drives of Altivar range. It has an Ohmic value of 16Ohms at 20°C. This braking resistor allows your variable speed drive to operate while braking to a standstill, by dissipating the braking energy and enables maximum transient braking torque. Its protection index is IP20. It weighs 7kg. This resistor is designed to be mounted on the outside of the enclosure.
