The VW3A58734 is a Schneider Altivar 58 dynamic brake resistor, rated for a 110 V supply and packaged as a single PCE unit, designed to dissipate braking energy from the U54N4 and U72N4 drive frames. It measures 66.04 mm deep by 83.82 mm wide by 331.978 mm tall, a compact footprint that fits within the Altivar 58 enclosure or adjacent panel space.
Lifecycle and sourcing
Schneider lists the VW3A58734 as discontinued; no official successor is named in the current catalog. Sourcing now runs through surplus and broker channels — an RFQ confirms available quantity and lead time for line-down or last-time-buy needs.
