Motor starter MS116-6.3A 1SAM250000R1009

Motor starter switches of the MS series – reliable protection for your motors

The MS116 motor starter switches are a compact and economical solution for protecting motors with a power of up to 15 kW (at 400 V) and a rated current of up to 32 A. These devices, only 45 mm wide, provide comprehensive protection against overload, short circuit and phase failure. They are ideal for both professional applications and end-users looking for reliable protection in electrical installations.

Functionality and construction

The MS116-6.3A switch is characterized by a solid construction and easy installation. It has a built-in disconnecting function, temperature compensation and a free-release mechanism. The knob with a clear switch position indication makes operation easier and allows for quick identification of the device status. The possibility of use in three-phase and single-phase installations increases its versatility. The rated continuous current at 6.3 A and the short-circuit breaking capacity of up to 75 kA at 400 V AC guarantee effective circuit protection.

Application and benefits

This model of switch finds wide application in various industries, construction and home installations. Thanks to its reliability and compact size, it is ideal for protecting electric motors in pumps, fans, conveyors and other equipment. It is worth noting the setting range of the overload release (4-6.3 A), which allows for precise adaptation to the load characteristics. Thermal protection protects the motor from overheating, and phase failure sensitivity prevents damage caused by voltage asymmetry. Complete enclosure design ensures it is ready for immediate installation and use. Main contact connection is realized by screw connections, which ensures a secure and durable electrical connection.
