ABB MS116-12 1SAM250000R1012 MS116 Manual Motor Starter 8.0-12A

ABB MS116-12 (article 1SAM250000R1012) is a compact manual motor starter - also known as a motor protection circuit breaker or manual motor protector - with a rated operational current of 12.0 A and an adjustment range of 8.0 to 12 A. It allows operators to switch motors on and off while protecting them against short-circuits, overload, and phase failures without the need for a separate fuse, and provides a rated service short-circuit breaking capacity of 25 kA at 400 VAC.

Technical specifications:

• Series: MS116-12
• ABB article number: 1SAM250000R1012
• EAN: 4013614348211
• Type: Manual motor starter (motor protection circuit breaker / manual motor protector)
• Current adjustment range: 8.0 - 12 A
• Rated operational current (Ie): 12.0 A
• Width: 45 mm
• Short-circuit breaking capacity (Ics): 25 kA at 400 VAC
• Trip class: 10A
• Phase compatibility: three-phase and single-phase

Features and benefits:

• Fuse-free protection against short-circuits, overload, and phase failures in one compact device
• Built-in disconnect function eliminates the need for a separate isolating switch
• Temperature compensation maintains consistent trip behavior across varying ambient conditions
• Trip-free mechanism prevents contacts from being held closed during an active fault condition
• Rotary handle with clear switch position indication for immediate visual confirmation of motor state

Applications:

• Manual starting and stopping of motors in industrial control panels and switchgear
• Overload and short-circuit protection of three-phase motors
• Single-phase motor protection where fuse-free operation is required
• Control installations requiring a compact 45 mm wide motor protection device with integrated disconnect

Also known as: ABB MS116-12, MS116-12 1SAM250000R1012, manual motor starter, motor protection circuit breaker, manual motor protector.
