MS116-0.4 A Motor starter 1SAM250000R1003

Motor starter switch – reliable protection for your installation

This three-pole motor starter switch MS116-0.4 is a compact and effective solution for protecting electric motors. It provides effective protection against overload, short circuit and phase failure, which translates to longer device life and work safety. The device is designed for manual switching on and off of motors, and its construction as a complete device in a housing facilitates installation and integration with the existing installation.

Design and application

The MS116-0.4 switch is characterized by a solid construction and precise workmanship. The use of a knob for operation ensures ease of use, and the screw connection of the main contacts guarantees secure and durable electrical connections. Designed to operate in circuits with a rated voltage of 690 V, it will perform perfectly in various industrial and commercial applications. The rated continuous current at 0.4 A and the overload release setting range of 0.25-0.4 A allow for precise adaptation to the needs of a specific application. Additionally, the sensitivity to phase failure increases work safety by protecting the motor from damage caused by the absence of one of the supply phases.

Key features and benefits

• Versatile protection: Protects motors against overload, short circuit and phase failure – minimizes the risk of failure and downtime.
• Compact dimensions: 45 mm width, 90 mm height and 85.6 mm depth make installation easy even in tight spaces.
• Precise adjustment: The overload release setting range (0.25-0.4 A) allows for optimal adaptation to the load characteristics.
• High short-circuit breaking capacity: Rated short-circuit breaking capacity Icu at 400 V, AC is as high as 100 kA – ensures effective disconnection in the event of a short circuit.
• Thermal-magnetic tripping method: Provides a quick response to overloads and short circuits, protecting the motor from thermal and mechanical damage.
• Safety of use: Thermal protection further increases the safety of the device and protects against overheating.
• Durable construction: Made of high-quality materials guarantees long life and reliable operation in harsh industrial conditions (IP20).
• Low power consumption: Power losses are only 5.1 W – minimizing energy consumption during device operation.
