ABB MS116-32 1SAM250000R1015 MS116 Manual Motor Starter 25-32A

The ABB MS116-32 (article 1SAM250000R1015) is a compact manual motor starter with a 45 mm width and a current setting range of 25 to 32 A. It is designed to manually switch motors on and off while providing fuse-free protection against short-circuits, overload, and phase failures. With a rated service short-circuit breaking capacity of 10 kA at 400 VAC and trip class 10A, it is suitable for both three-phase and single-phase motor applications.

Technical specifications:

• Series: MS116-32
• ABB article number: 1SAM250000R1015
• EAN: 4013614405679
• Current setting range: 25 - 32 A
• Rated operational current (Ie): 32.0 A
• Rated service short-circuit breaking capacity (Ics): 10 kA at 400 VAC
• Trip class: 10A
• Width: 45 mm
• Phase compatibility: Three-phase and single-phase

Features and benefits:

• Fuse-free protection against short-circuits, overload, and phase failure in a single compact device, reducing panel component count.
• Built-in disconnect function allows safe isolation of the motor branch circuit without a separate isolator or switch.
• Temperature compensation keeps trip thresholds consistent across varying ambient conditions.
• Trip-free mechanism prevents the device from being held in the ON position during an active fault condition.
• Rotary handle with clear switch position indication provides immediate visual confirmation of ON or OFF status.

Applications:

• Manual starting and stopping of three-phase induction motors in industrial machinery and equipment.
• Motor branch circuit protection in control panels and switchgear enclosures.
• Single-phase motor installations requiring compact overload and short-circuit protection without a fuse.
• Machine builder applications where accessory locking devices are needed to prevent unauthorized changes to switch settings.
