Motor starter MS18-10A 004600349

Motor starter – reliable motor protection

This three-pole MS18-10A motor starter from ETI Polam is a key element in protecting electrical installations powering motors. It provides effective protection against overload and short circuit, and also protects against the effects of phase failure, which is particularly important in demanding industrial and commercial applications. The device is designed for permanent installation and is characterized by high reliability and durability.

Functionality and application

The MS18-10A starter is designed to protect motors with a power of up to 4 kW at 400 V and 2.5 kW at 230 V. Its overload release setting range (6.3 – 10 A) allows for precise adjustment to the load characteristics. The thermal-magnetic tripping method guarantees a quick response in the event of a failure, minimizing the risk of damage to connected devices. The applications of this starter include:

• Protection of electric motors in industry,
• Protection of installations in commercial and public buildings,
• Use in automation and control systems.

Characteristics and benefits

The starter's construction is based on solid materials, which translates into long life and resistance to environmental conditions. The IP20 degree of protection provides basic protection against contact and ingress of solid objects. The rated short-circuit breaking capacity of 50 kA at 400 V AC guarantees safety even in the event of serious disturbances in the electrical network. Additionally:

• Phase failure sensitivity: Protects the motor from damage caused by voltage asymmetry.
• Frame terminals: Enable easy and secure connection of wires.
• Permanently mounted device: Ensures stability and mounting safety.
• Wide operating voltage range (230…690 V): Allows use in various electrical installations.
• Thermal protection: Protects against motor overheating during prolonged load.

Thanks to these features, the MS18-10A starter is a comprehensive solution for professionals looking for reliable and effective protection for electric motors.
