Description

The ABB MS116-10 is a manual motor starter and protector for three-phase motors up to 10 A full-load current, providing integrated thermal overload protection, electromagnetic short-circuit release, and manual motor isolation in a single DIN rail-mounted unit. As part of ABB’s MS116 series, this device is designed to simplify the protection and control of motors in the 3–4 kW range at 400 V, eliminating the requirement for a separate circuit breaker and overload relay in many applications. The current setting is adjustable within the device’s rated range, allowing precise calibration to the motor’s nameplate full-load current.

The MS116-10 complies with IEC 60947-4-1 and IEC 60947-2, providing Class 10 tripping characteristics appropriate for standard induction motors. The thermal overload element gives reliable protection against sustained overload conditions, while the electromagnetic release provides fast disconnection under short-circuit conditions. Phase failure detection provides additional motor protection in the event of a supply phase loss, which would otherwise cause excessive current in the remaining phases and rapid motor overheating.

Compatible with ABB’s MS116 accessory range, including front-mount and side-mount auxiliary contact blocks and remote voltage releases, the MS116-10 can be integrated into automated motor monitoring and control systems. It mounts on 35 mm DIN rail and is widely used in motor control panels for pumps, fans, compressors, conveyors, and general industrial drives. Its compact design, combined ABB protection co-ordination, and ease of installation make it a preferred choice for electrical contractors and panel builders working on industrial and commercial motor control projects.
