Product questions
What motor current range does the ABB MS116-0.4 cover?
Its adjustable overload setting range is 0.25–0.40 A. The motor’s rated current must fall within that range; also verify the voltage and protection requirements before selection.
What protection does 1SAM250000R1003 provide?
The MS116-0.4 provides thermal overload and electromagnetic short-circuit protection, with phase-loss sensitivity. It also allows manual on/off switching and has a disconnect function.
What is its short-circuit breaking capacity at 400 V AC?
ABB’s MS116 data sheet lists a rated service breaking capacity (Ics) of 50 kA and ultimate breaking capacity (Icu) of 100 kA at 400 V AC for the MS116-0.4. Check the applicable rating and installation conditions for the circuit.
Can this motor protection breaker be used with a single-phase motor?
ABB lists the MS116 for single- and three-phase applications. Suitability depends on motor current, voltage, protection requirements and the correct connection arrangement; consult the ABB documentation and a qualified electrical professional.
