Motor starter with thermal and electromagnetic trip unit with neutral conductor N M250 (6.3A - 10A) 606809

Motor starter M250 is a reliable protection for electric motors against the effects of overloads and short circuits. It is a complete device in a housing, designed to protect circuits where significant loads may occur during normal operation. Equipped with a thermal and electromagnetic release, it provides effective protection against both long-term overloads and sudden short circuits.

This model, with a rated current of 10A, has a neutral conductor N, which increases its functionality and range of applications. This makes it ideal for installations requiring a neutral wire connection. The circuit breaker is characterized by a high short-circuit breaking capacity of 6kA at 400V AC, which guarantees the safety of the installation in the event of a serious failure.

Construction features and application

M250 circuit breakers 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. The availability of additional NO/NC auxiliary contacts and short-circuit indicators allows you to expand the functionality of the circuit breaker and integrate it with monitoring and control systems. The window for describing the installation facilitates identification and servicing of the device.

• Motor protection: Protects electric motors from damage caused by overloads and short circuits, ensuring the continuity of the installation.

• Adjustment range: The ability to adjust the setting range of the overload release from 6.3 to 10 A allows for precise adaptation to the specifics of the load and avoids unnecessary shutdowns.

• High breaking capacity: The short-circuit breaking capacity of 6kA at 400V AC guarantees the safety of the installation even in the event of a serious failure, minimizing the risk of equipment damage.

• Mounting: Quick and easy mounting on a DIN rail in electrical panels facilitates installation and servicing of the device.

• Connections: Ensures secure and durable connection of wires thanks to screw connections, which translates into the reliability of the entire system.

User parameters

The M250 circuit breaker has been designed with the convenience of installers and reliability for end-users in mind. Its compact dimensions (89 mm high, 45 mm wide and 72.5 mm deep) allow for mounting even in tight spaces. The IP3X degree of protection protects against access to hazardous live parts and against the influence of the external environment. The device operates in the range of voltages from 230 to 500 V AC and frequencies of 50-60 Hz, which makes it a universal solution for various industrial and commercial applications. The rated operating power for AC-3 is 7.5 kW at 400 V and 4.5 kW at 230 V, which confirms its efficiency and reliability in working with various types of electric motors.
