Motor starter MS18-0.25A 004600341

Motor starter – reliable protection for your devices

This three-pole ETI MS18-0.25A motor starter is a key element in protecting the electrical installation powering motors. It provides effective protection against overload and short circuit, and also offers additional functions such as phase failure control. It is a solution for both professional installers and end users looking for reliable and safe protection.

Design and application

The MS18-0.25A starter is designed for permanent installation and is characterized by an IP20 protection class, which means it should be installed indoors, in dry places. Its thermomagnetic design ensures a quick response to irregularities in the circuit. It can be used to protect motors with a power of up to 0.06 kW at 400V AC. Thanks to the adjustable range of the overload release setting (0.16…0.25A), it can be adapted to the specific needs of a given motor.

Key features and benefits

• Versatile application: ideal for protecting electric motors, but can also function as a main or emergency switch.
• Overload and short circuit protection: ensures the safety of the installation and connected devices.
• Phase failure control: an important function that increases the safety of motor operation – detects the absence of one of the phases and disconnects the circuit, preventing damage.
• Adjustable setting range: allows precise adjustment to the load characteristics (range 0.16…0.25A).
• Rated short-circuit breaking capacity: 50 kA at 400V AC – guarantees effective disconnection of the circuit in the event of a short circuit.
• DIN rail mounting: simplifies and speeds up installation in electrical switchboards.
• Frame terminals: provide a secure and durable connection of wires.
• Polish production (ETI Polam): guarantees quality and service availability.

This starter is particularly recommended where high reliability and precise motor protection are required – both in domestic and industrial applications. Thanks to its solid construction and advanced functions, it is an investment in safety and long-term operation of devices.
