Product questions
What does the ABB MS132-16T protect?
The MS132-16T is designed for primary-side protection of control transformers against overload and short circuit. It also provides manual disconnection. Selection must be checked against the transformer and installation requirements.
What current range and short-circuit trip setting does 1SAM340000R1011 have?
The adjustable overload setting range is 10–16 A; the rated instantaneous short-circuit setting is fixed at 320 A. ABB specifies trip class 10. The transformer nominal current should fall within the adjustable range.
What is the MS132-16T breaking capacity at 400 V AC?
ABB specifies both Ics and Icu as 100 kA at 400 V AC. Breaking capacity varies with voltage; suitability also depends on the prospective fault current and the applicable installation requirements.
How is the MS132-16T mounted and connected?
The three-pole MS132-16T has screw terminals and mounts on a 35 mm TH35-7.5 or TH35-15 DIN rail. Its housing is IP20, while the main-circuit terminals are IP10. Confirm enclosure and wiring requirements for the installation.
