Product questions
What current range does the ABB MS116-25 cover?
The MS116-25 has an adjustable overload setting range of 20–25 A and a rated operational current of 25 A. Check the motor nameplate current and the circuit requirements when selecting it.
What is its short-circuit breaking capacity at 400 V AC?
At 400 V AC, the MS116-25 has a rated service short-circuit breaking capacity (Ics) of 10 kA and rated ultimate capacity (Icu) of 16 kA. Confirm the prospective fault current and applicable protection requirements for the installation.
Can the MS116-25 be used with a single-phase motor?
The MS116-25 is described as suitable for single-phase and three-phase motor applications. Suitability depends on the motor and installation; verify the motor nameplate, connection arrangement and applicable ABB instructions before use.
What motor power is rated for the MS116-25 at 400 V?
Its rated three-phase operational power is 11 kW at 400 V in AC-3 duty. Power alone does not establish suitability: check motor current and the circuit conditions as well.
What protection and switching functions does this starter provide?
The MS116-25 provides manual motor switching and protection against overload, short circuit and phase failure. It has a rotary handle and a disconnect function; its overload trip class is 10A.
