Applications & Use Cases

The ABB MS116-10 is widely specified by electrical engineers and panel builders for direct-on-line motor starters, pump control panels, conveyor systems, compressor protection, and HVAC motor circuits. Its 50 kA breaking capacity at 400 VAC makes it suitable for installation close to high-energy supply points without additional current limiting fuses. The compact 45 mm footprint of the MS116-10 conserves valuable panel real estate while the broad certification portfolio — spanning CE, UL, CSA, CCC, EAC, and RMRS — simplifies global project compliance.
