MS116-0.63A Motor starter 1SAM250000R1004

Motor protection circuit breakers MS series – reliable protection for your motors

The MS116-0.63A motor protection circuit breaker is a compact and effective solution for protecting motors up to 0.18 kW (at 400V). The device combines overload and short-circuit protection, providing comprehensive protection for the electrical installation and connected devices. It is ideal for both professional and home installations where reliability and safety are required.

Construction and operating principle

The MS116-0.63A circuit breaker is based on the principle of thermal-magnetic tripping. This means that in the event of a motor overload, the thermal element causes a delayed circuit interruption, protecting the motor from overheating. In the event of a short circuit, the quick magnetic tripping immediately disconnects the power supply, minimizing the risk of damage and fire. Additionally, phase failure sensitivity provides protection against voltage asymmetries, which can lead to incorrect motor operation and damage.

Application and benefits

The MS116-0.63A circuit breaker is widely used in protecting:

• Single-phase and three-phase motors up to 0.18 kW (400V).
• Pumps, fans, compressors and other devices using electric motors.
• Industrial installations, workshops and public buildings.
• Home electrical installations powering motor-driven devices.

Why choose MS116-0.63A?

• Compact dimensions: A width of only 45 mm allows for easy mounting in tight switchboards.
• Versatility: Can be used in three-phase and single-phase installations.
• High short-circuit breaking capacity: The rated short-circuit breaking capacity Icu is as high as 100 kA at 400V AC, guaranteeing effective protection in the event of a short circuit.
• Thermal protection: Protects the motor from overheating and damage caused by overload.
• Phase failure sensitivity: Provides additional safety by detecting voltage asymmetry.
• Simple installation: Screw connection of the main contacts facilitates connection of the wires.
• Durable construction: Made of high-quality materials ensures a long service life of the device.
• Compliance with standards: The device meets applicable safety standards, confirming its reliability and safety of use (IP20).

This circuit breaker is not only a protective element – it is an investment in the long-term and trouble-free operation of your electrical devices!
