Why Choose the ABB 1SAM250000R1006 MS116-1.6 Manual Motor Starter?
The ABB 1SAM250000R1006, also designated the MS116-1.6, is a compact and reliable manual motor starter and motor protection circuit breaker designed for switching and protecting motors in industrial machinery and control systems. It combines manual control, disconnection, thermal overload protection and electromagnetic short-circuit protection within a single 45 mm-wide device.
The adjustable thermal release covers motor currents from 1.00 to 1.60 A, allowing the protection setting to be matched to the motor’s rated current. Its phase-failure sensitivity, temperature compensation and Class 10A tripping characteristic provide dependable protection against sustained overloads and abnormal operating conditions.
With a rated motor power of 0.55 kW at 400 V AC and a rated service short-circuit breaking capacity of 50 kA at 400 V AC, the MS116-1.6 is suitable for small motors used in pumps, fans, conveyors and production equipment. Its rotary operating handle provides clear switching indication, while the trip-free mechanism ensures that protective tripping cannot be prevented by holding the handle in the ON position.

Reliable Motor Control and Protection
Manual motor starters such as the ABB MS116 use thermal and electromagnetic releases to protect connected motors. The adjustable thermal release responds to sustained overloads, while the electromagnetic release disconnects the circuit rapidly when a high short-circuit current occurs.
The MS116-1.6 can be used independently for local motor switching or combined with a compatible contactor to form a remotely controlled motor starter. ABB auxiliary contacts, signalling contacts, voltage releases, busbars, power in-feed blocks and locking devices are available to adapt the installation to different control requirements.
Typical Applications
- Motors rated up to approximately 0.55 kW at 400 V AC.
- Pumps, fans and ventilation equipment.
- Small conveyors and material-handling systems.
- Machine tools and production equipment.
- Industrial control panels and motor starters.
- Local motor switching and isolation.
