Product Description

The ABB MS116 (often called a motor protection circuit breaker / manual motor protector) combines overload (thermal) and short-circuit (magnetic) protection with a front rotary isolator—ideal for direct-on-line (DOL) starters and local motor isolation. The range covers adjustable FLA settings up to 32 A (variant-dependent) and is designed for fuse-less protection with fast magnetic tripping on faults. Typical performance includes Ics 50 kA @ 400 V and Icu up to 75 kA, with trip class 10A, temperature compensation, trip-free mechanism, and clear ON/OFF/TRIP indication. The 45 mm module width saves panel space; accessories (aux/signal contacts, shunt/undervoltage releases, lockable handles, feed-in blocks) are shared with MS132 to simplify stocking. Use with ABB contactors to build compact DOL/RV starters
