The ABB MS116-25 is a genuine ABB MS116 manual motor starter, adjustable from 20-25 A for motors up to 11 kW at 400 V. The MS116-25 manual motor starter (also known as motor protection circuit breaker or manual motor protector) is a compact 45 mm width device with a rated operational current of Ie = 25.0 A. This device is used to manually switch on and off motors and to protect them reliably and without the need for a fuse from short-circuits, overload and phase failures. The manual motor starter offers a rated service short-circuit breaking capacity Ics = 10 kA at 400 VAC and trip class 10A. Further features are the build-in disconnect function, temperature compensation, trip-free mechanism and a rotary handle with a clear switch position indication. The manual motor starter is suitable for three- and single-phase applications. Auxiliary contacts, signaling contacts, undervoltage releases, shunt trips, 3-phase bus bars, power in-feed blocks and locking devices for protection against unauthorized changes are available as accessory. The MS116 is the most common motor protection breaker on European built machines and pump packages installed across Iraq, Saudi Arabia, the UAE and the wider Arab region, and it is the part maintenance teams replace after repeated short-circuit trips or handle damage. RendatSP stocks the full setting range together with the HK1/HKF1 auxiliary contacts and the matching ABB AX/AF contactors.

Frequently Asked Questions
What is the setting range of the ABB MS116-25?
The thermal overload setting is adjustable from 20-25 A; the magnetic short-circuit release is fixed at 375 A, according to ABB technical data.
What motor size does it protect?
Up to 11 kW three-phase at 400 V (AC-3), matching a motor with full-load current inside the 20-25 A range.
What is its breaking capacity?
Rated service short-circuit breaking capacity Ics 10 kA at 400 VAC, so it can be used without back-up fuses in most 400 V panels.
Which accessories fit the MS116-25?
ABB HK1/HKF1 auxiliary contacts, SK1 signalling contacts, UA1 undervoltage releases, AA1 shunt trips, 3-phase busbars and the MS116 handle lock, all available from RendatSP.
Can it replace an MS116 with a different setting range?
Only if the motor full-load current falls inside the new setting range; send RendatSP the motor nameplate current and we will confirm the correct MS116 rating.
Is the ABB MS116-25 supplied by RendatSP genuine?
Yes. RendatSP supplies the genuine ABB MS116-25, ABB order code 1SAM250000R1014, in ABB packaging. Send us the type code from your existing part or panel label and we will confirm the exact match.
How fast can RendatSP quote and ship the MS116-25?
Quotes are sent within hours and orders ship worldwide, including Iraq, Saudi Arabia, the UAE and the wider Middle East.
