Motor starter M250 1NO/1NC (18A - 25A) 606832

Motor starter – reliable protection for your devices

The M250 motor starter is a key device in any electrical installation, providing effective protection for motors against overloads and short circuits. Designed for both professional installers and end users, it guarantees safety and reliable operation. A complete device in a housing, ready for mounting on a DIN rail, simplifies and speeds up installation.

Functionality and technical parameters

This three-pole (3P) starter with a rated continuous current of 25A is perfect for applications requiring protection of motors up to 7.5 kW at 400V and 4.5 kW at 230V. The overload release setting range (18-25A) allows for precise adjustment to the load characteristics, and the short-circuit release range (280-420A) ensures a quick response in the event of a failure. The thermal-magnetic tripping method guarantees comprehensive protection, combining the advantages of thermal and short-circuit protection. An integrated auxiliary contact expands the possibilities of using the starter in more complex control systems.

• Versatile application: ideal for protecting electric motors in various industrial and domestic applications.

• Precise adjustment: the overload release setting range allows adaptation to the specifics of the load.

• Fast reaction: high short-circuit capacity (3kA at 400V AC) ensures a rapid intervention in the event of a short circuit.

• Easy installation: compact dimensions (45 mm width, 89 mm height, 72.5 mm depth) and DIN rail mounting simplify installation and integration with existing infrastructure.

• Durable construction: made of high-quality materials, ensuring long-lasting and reliable operation.

• Safety: IP3X protection degree protects against access to hazardous live parts.

Construction and application

The M250 starter is characterized by a solid construction and high quality of workmanship. Screw connection of the main contacts ensures a secure and durable connection of the wires, and the lever of the actuator enables easy operation. The device is designed to operate in an ambient temperature from -5°C to 40°C, making it suitable for most operating conditions. Lack of phase failure sensitivity increases resistance to disturbances in the power supply network. M250 starters are available in various versions – with only a thermal release (M 250 T), electromagnetic (M 250 M) or a combination of both (M 250), allowing you to choose the optimal solution for specific needs.
