ABB MS116-20 1SAM250000R1013 MS116 Manual Motor Starter 16-20A

The ABB MS116-20 (article 1SAM250000R1013) is a compact manual motor starter with a current setting range of 16 to 20 A and a housing width of 45 mm. It manually switches 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 suited to both three-phase and single-phase motor circuits.

Technical specifications:

• Series: MS116-20
• ABB article number: 1SAM250000R1013
• EAN: 4013614405655
• Current setting range: 16 to 20 A
• Rated operational current (Ie): 20.0 A
• Housing width: 45 mm
• Short-circuit breaking capacity (Ics): 10 kA at 400 VAC
• Trip class: 10A
• Compatible with three-phase and single-phase applications

Features and benefits:

• Built-in disconnect function enables safe isolation of the motor circuit without additional switching devices
• Temperature compensation keeps tripping behaviour consistent across varying ambient conditions
• Trip-free mechanism prevents manual override of the trip contact during a fault, maintaining circuit protection at all times
• Rotary handle with clear switch position indication allows quick visual confirmation of on/off state
• Extensive accessory range - auxiliary contacts, signalling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power in-feed blocks, and locking devices - supports flexible panel layouts and security requirements

Applications:

• Starting and protecting three-phase motors in industrial control panels and machine tools
• Motor branch circuit protection where fuse-free operation is preferred
• Single-phase motor protection in light industrial or commercial equipment
• Installations requiring manual motor isolation with locking against unauthorised operation
