MS116-0.16A Motor starter switch 1SAM250000R1001

Motor protection switch – reliable protection for your motors

Motor protection switch MS116-0.16A is a three-pole device designed for comprehensive protection of electric motors. It provides effective protection against overloads, short circuits, phase failure and other irregularities in the circuit. Its compact design and DIN rail mounting make it ideal for use in industry, construction and commercial installations.

Construction and application

The device uses a thermal-magnetic tripping principle, which means it reacts to both the temperature increase caused by overload and the sudden increase in current in the event of a short circuit. The current adjustment knob allows for precise adjustment of the switch characteristics to the needs of a specific motor. Protection against phase failure protects the motor from damage in the event of loss of one of the supply phases – a situation that can lead to serious failures. The MS116-0.16A switch is a complete device in a housing, ready for mounting and immediate use.

Key features and benefits

• Wide adjustment range: Current adjustment in the range of 0.1 – 0.16 A allows adaptation to various motor loads.
• High short-circuit breaking capacity: Rated short-circuit breaking capacity Icu of 100 kA at 400 V guarantees the safety of the installation even in the event of high short-circuit currents.
• Phase failure protection: This function minimizes the risk of motor damage caused by voltage asymmetry.
• Compact dimensions: Dimensions of 90 x 45 x 85.6 mm allow for easy mounting in tight spaces.
• Durable construction: Made of high-quality materials ensures reliable operation for a long time.
• Thermal protection: Built-in thermal protection protects the motor from overheating and damage caused by prolonged overload.
• Easy operation: Current adjustment with a knob is intuitive and quick, making device configuration easier.

Technical parameters in practice

Rated continuous current Iu of 0.16 A means that the switch is designed to protect motors with a relatively low power consumption – about 0.03 kW at 230 V or 400 V (AC-3). Power losses of only 5.1 W minimize the impact of the device on the energy efficiency of the installation. Protection class IP20 provides protection against accidental contact, but does not protect against water or dust – therefore, the device should be used in dry and clean rooms. The switch meets the requirements of IEC 60947-1/IEC 60947-2/EN60 P47-1/EN60 (47-2) standards and has UL and CSA certificates confirming its safety and quality.
