ABB MS116-1.0 1SAM250000R1005 MS116 Manual Motor Starter 0.63-1.0A

The ABB MS116-1.0 (article 1SAM250000R1005) is a compact manual motor starter - also referred to as a motor protection circuit breaker or manual motor protector - with a current setting range of 0.63 to 1.0 A and a rated operational current of 1.0 A. Housed in a 45 mm wide body, it allows operators to switch motors on and off manually while delivering fuse-free protection against short-circuits, overload, and phase failures. Short-circuit breaking capacity is rated at Ics = 50 kA at 400 VAC with trip class 10A.

Technical specifications:

• Series: MS116-1.0
• ABB article number: 1SAM250000R1005
• EAN: 4013614320286
• Current setting range: 0.63 - 1.0 A
• Rated operational current (Ie): 1.0 A
• Rated service short-circuit breaking capacity (Ics): 50 kA at 400 VAC
• Trip class: 10A
• Housing width: 45 mm
• Suitable for three-phase and single-phase applications

Features and benefits:

• Fuse-free motor protection - guards against short-circuits, overload, and phase failures without requiring a separate fuse
• Built-in disconnect function provides safe isolation from the supply in a single device
• Trip-free mechanism ensures reliable tripping regardless of handle position
• Temperature compensation maintains accurate overload protection across varying ambient conditions
• Rotary handle with clear switch position indication for straightforward operation and instant status reading

Applications:

• Manual starting and stopping of small motors in industrial and commercial equipment
• Motor branch circuit protection in three-phase and single-phase control panels
• Installations requiring a combined switch, overload protector, and disconnector in a single 45 mm wide unit
• Control cabinets where locking accessories are needed to prevent unauthorized operation
