Product questions
What is ABB 1SAM340000R1006 designed to protect?
It is the MS132-1.6T circuit breaker, designed for primary-side control transformer protection against overload and short circuit. Suitability depends on the transformer and circuit ratings.
What is the overload setting range for MS132-1.6T?
The adjustable overload setting range is 1.0–1.6 A. ABB advises choosing a breaker whose range includes the actual nominal current; other circuit requirements must also be checked.
What are the short-circuit trip setting and breaking capacity?
The instantaneous short-circuit setting is 32 A. ABB lists both service and ultimate short-circuit breaking capacity as 100 kA at 400 V AC; verify the applicable circuit conditions.
Does the MS132-1.6T have screw terminals and DIN-rail mounting?
Yes. This T version has screw terminals and mounts on TH35-7.5 or TH35-15 DIN rail. Its three-pole construction and circuit ratings should be checked against the intended installation.
