Set overload protection to the actual motor nameplate current. The stated Ics and Icu are distinct 400V AC open-device ratings from the referenced ABB catalogue; other voltages and enclosed installations have separate ratings. Front contact choices are one module; the right-side slot allows up to two auxiliary modules or one signalling module. Shunt and undervoltage releases are alternatives on the left side. Release AC voltage and frequency must match.
Accessories and installation
Choose the front contact arrangement and terminal type, or a right-side auxiliary/alarm module with its contact arrangement and quantity. AC releases are selected by both frequency and voltage. IB132-G/Y and DMS132-G/Y are separate installation items; the base device is not included in these accessory codes.
The IB132 enclosure permits one side module, one UA1/AA1 release and one front HKF1 module. Selecting an enclosure restricts the side quantity to one. Enclosed operating current and conditional short-circuit ratings must follow ABB instruction 2CDC131028M6805 Rev E; these do not replace open-device Ics/Icu values.
