Product questions
What does the ABB MS132-12T protect?
The MS132-12T is designed to protect the primary side of control transformers against overload and short circuit. It also provides a manual disconnect function.
What current range does the MS132-12T cover?
Its overload setting range is 8–12 A, and its rated operational current is 12 A. Confirm the transformer primary current and the rest of the circuit requirements before selection.
How does the MS132-12T handle transformer inrush current?
Its instantaneous short-circuit setting is fixed at 240 A, or 20 times its 12 A rated operational current. This higher magnetic threshold is intended to accommodate transformer inrush.
What is the short-circuit breaking capacity of the MS132-12T?
ABB specifies a rated service short-circuit breaking capacity of 100 kA at 400 V AC. Breaking capacity depends on voltage, so verify the rating and coordination for the actual installation.
How is the MS132-12T mounted and connected?
The three-pole device supports DIN-rail mounting and has screw terminals for the main circuit. It is 45 mm wide and has a lockable rotary handle.
