Schneider Electric MSA25A440V16-24A Motor Starter Assembly

Description:

The Schneider Motor Starter Assembly is a preassembled motor control unit combining a contactor and thermal overload relay for industrial motor applications. Commonly installed in pumps, conveyors, compressors, fans, and manufacturing machinery requiring reliable motor starting and overload protection. Maintenance teams, OEMs, and system integrators use this starter assembly for equipment repairs, control panel retrofits, and replacement of existing motor starter systems. The assembly features a 25A contactor with a 440 VAC coil and an adjustable thermal overload relay rated from 16 to 24 A.

Applications:

The Schneider Motor Starter Assembly is designed to provide manual and remote motor control with integrated overload protection in industrial environments. It is commonly used in motor control centers, conveyor systems, pumping stations, compressors, HVAC equipment, and manufacturing machinery where reliable motor starting and thermal overload protection are required to minimize downtime and ensure safe operation. Schneider TeSys starters combine contactors and overload relays into compact assemblies for IEC motor control applications.
