Product questions
What is the ABB 1SAM340000R1009 designed to protect?
The MS132-6.3T is designed for primary-side protection of control transformers against overload and short circuit. Confirm the transformer ratings and equipment serial number before selecting it for a specific installation.
What are the overload and instantaneous trip settings?
The overload setting range is 4.0–6.3 A. Its fixed instantaneous short-circuit setting is 126 A, or 20 times the rated operational current, to accommodate transformer inrush.
What is the breaking capacity of the MS132-6.3T at 400 V AC?
The rated service breaking capacity (Ics) and ultimate breaking capacity (Icu) are each 100 kA at 400 V AC. Check the installation fault level and applicable ratings before selection.
How is the MS132-6.3T connected and operated?
It is a three-pole breaker with screw terminals and a lockable rotary handle. It provides manual disconnection and an indication of short-circuit tripping.
