Description

The ABB S500UC is the DC version of the S500 supplementary protector (UL 1077), rated up to 250 VDC (1-pole), 500 VDC (2-pole) and 600 VDC (3- and 4-pole) with a 30 kA interrupting rating.

K curve: close thermal protection with a high magnetic threshold, so motors, transformers and other inductive loads start without nuisance tripping.

Choose the number of poles and the rated current below; the matching ABB catalogue number is shown and included in your quotation request.

The rated-current options are the adjustable setting ranges of each device.
