The ABB MS116-16 is a compact motor protection circuit breaker designed for reliable motor control and protection in industrial applications. It provides comprehensive protection against overload, short-circuit, and phase loss for three-phase motors up to 7.5kW at 400V. With a 16A adjustable current range and Class 10A tripping characteristic, it ensures safe motor starting without nuisance tripping. The unit features a 50kA breaking capacity at 400V, temperature compensation from -25°C to +60°C, and a lockable handle for safety isolation. Its compact 45mm width saves panel space, while modular design allows easy integration with contactors and auxiliary contacts.

Frequently Asked Questions (FAQ)
What is the difference between MS and MO series motor starters?
The MS series features full thermal-magnetic trip protection, safeguarding against both overloads and short circuits. The MO series provides magnetic-only trip protection, primarily designed for short-circuit protection when paired with separate overload relays.
Does the MS116 provide phase failure protection?
Yes, the MS116 motor protection circuit breaker features integrated phase failure sensitivity, helping prevent motor burnout in case of an unbalanced or lost phase.
What is the breaking capacity of the MS116 series at 400V?
The short-circuit breaking capacity varies by current rating: up to 10A offers 50 kA Icu/Ics, 12A provides 25 kA, 16A provides 16 kA, 20–25A offers 15 kA (10 kA Ics), and 32A achieves 10 kA.
What ambient temperature range can the MS116 operate in?
The MS116 is temperature-compensated and operates reliably within an ambient air temperature range of -25°C to +55°C.
How does the MS116 differ from the MS132?
While both share a compact 45mm width and rated current up to 32A, the MS132 includes an ON/OFF/TRIP 3-position handle, magnetic trip indication, and a built-in lockable handle without requiring extra accessories.
