Product questions
What does ABB 1SAM340000R1013 protect?
The MS132-20T is designed for overload and short-circuit protection on the primary side of control transformers. It also has a manual disconnect function.
What is the MS132-20T overload setting range?
The adjustable overload setting range is 16–20 A, with a rated operational current of 20 A. The transformer nominal current must fall within the setting range; check the full electrical design before selection.
What is the short-circuit trip setting and breaking capacity?
The instantaneous short-circuit setting is fixed at 400 A, intended to accommodate transformer inrush. The rated service breaking capacity is 100 kA at 400 V AC; breaking capacity and any backup protection depend on voltage.
Can the MS132-20T be mounted on a DIN rail, and what terminals does it use?
Yes. ABB specifies TH35-7.5 and TH35-15 mounting rails. This MS132-20T version uses screw terminals; the housing is IP20 and the main-circuit terminals are IP10.
