Application and model selection
The SKB3400055 is a Commander SK AC drive from Control Techniques. Its original-model row in the manufacturer crossover guide identifies a 400–480 V three-phase supply, 0.75 hp rating and frame B.

Installation and equipment scope

Record the existing drive parameters, terminal wiring and fitted options. Include accessories in the enquiry by their own references.
Quotation enquiries
Send Seven Star LLC the complete model reference, quantity, supply voltage, motor nameplate and installation details. Identify any required keypad, communication module, reactor or braking accessory separately. A power rating alone does not establish a suitable replacement.
