ABB MS116-2.5 1SAM250000R1007 MS116 Manual Motor Starter 1.6-2.5A

The ABB MS116-2.5 (article 1SAM250000R1007) is a compact 45 mm wide manual motor starter with a current setting range of 1.6 A to 2.5 A. It lets operators switch motors on and off manually while guarding them against short-circuits, overload, and phase failures without requiring a fuse. A rated service short-circuit breaking capacity of 50 kA at 400 VAC and trip class 10A make it well suited to demanding motor protection duties.

Technical specifications:

• Series: MS116-2.5
• ABB article number: 1SAM250000R1007
• EAN: 4013614320309
• Current setting range: 1.6 A - 2.5 A
• Rated operational current (Ie): 2.5 A
• Rated service short-circuit breaking capacity (Ics): 50 kA at 400 VAC
• Trip class: 10A
• Device width: 45 mm
• Phase compatibility: Three-phase and single-phase

Features and benefits:

• Built-in disconnect function removes the need for a separate isolating device in the circuit
• Fuse-free protection against short-circuits, overload, and phase failures simplifies panel design
• Temperature compensation keeps tripping behavior consistent across varying ambient conditions
• Trip-free mechanism prevents contacts from being held closed during a fault
• Rotary handle with clear switch position indication gives instant visual confirmation of device state
• Broad accessory range - auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power in-feed blocks, and locking devices available separately

Applications:

• Direct-on-line starting and protection of small three-phase or single-phase motors
• Motor protection in HVAC systems, pumps, and fans
• Machine tool and conveyor drive control panels
• Industrial motor circuits up to 2.5 A requiring fuse-free overload and short-circuit protection

Also known as: ABB MS116-2.5, MS116-2.5 1SAM250000R1007, manual motor starter, motor protection circuit breaker, manual motor protector.
