Product questions
What motor current range does ABB MS116-16 cover?
The adjustable thermal overload range is 10–16 A. The motor rated current must fall within that range; also check the supply, starting conditions and prospective fault current before selecting the device.
What is the MS116-16 short-circuit breaking capacity at 400 V?
At 400 V AC, ABB lists both the service breaking capacity (Ics) and ultimate breaking capacity (Icu) as 16 kA. Check the prospective fault current and the applicable backup protection requirements for the installation.
Can the MS116-16 protect a 7.5 kW motor?
ABB lists 7.5 kW at 400 V for three-phase AC-3 operation. Power alone does not establish suitability: check the motor nameplate current against the 10–16 A setting range and verify the full circuit ratings.
Can the MS116-16 be used with a single-phase motor?
ABB describes the MS116 as suitable for single- and three-phase applications. It is a three-pole device; the correct connection and suitability depend on the circuit and motor ratings. Refer to ABB’s documentation and have the installation assessed by a qualified electrician.
What protection does the ABB MS116-16 provide?
It combines adjustable thermal overload protection with electromagnetic short-circuit protection and phase-loss sensitivity. Its overload trip class is 10A; the rated instantaneous short-circuit setting is 240 A.
