Product questions
What does ABB 1SAM340000R1004 protect?
The MS132-0.63T is designed for primary-side protection of control transformers against overload and short circuit. It also provides manual disconnection. Confirm the transformer nameplate and system requirements before selection.
What current range does the MS132-0.63T cover?
Its adjustable overload setting range is 0.40–0.63 A, and its rated operational current is 0.63 A. The transformer’s actual nominal current must fall within the setting range.
What is the breaking capacity at 400 V AC?
ABB lists both the rated service breaking capacity (Ics) and ultimate breaking capacity (Icu) as 100 kA at 400 V AC. The required capacity depends on the available fault current and application.
Does the 1SAM340000R1004 use screw terminals and DIN-rail mounting?
Yes. This MS132-0.63T version has screw terminals and supports TH35-7.5 and TH35-15 mounting rails. Verify the existing device and available space before ordering.
