Motor starter with thermal and electromagnetic trip unit with neutral conductor N M250 (1.6A - 2.5A) 606806

M250 series motor circuit breakers – reliable motor protection

Motor circuit breakers M250 are devices designed to protect electric motors from the effects of overloads and short circuits. They provide comprehensive protection for power circuits, especially where short-term load increases may occur during normal operation. Model 606806, with an overload trip setting range of 1.6 – 2.5 A, is ideal for applications requiring precise adjustment and reliability. A design with a neutral conductor N increases the safety and functionality of the installation.

Construction and application

The M250 circuit breaker is a complete device in a housing, designed for mounting on a DIN rail. Its thermal-magnetic construction guarantees an effective response to both overloads (thermal trip) and short circuits (magnetic trip). The rated continuous current of 2.5 A and the short-circuit capacity of 6 kA at 400 V AC provide adequate protection for motors with a power of up to 7.5 kW (AC-3, 400 V) or 4.5 kW (AC-3, 230 V). This circuit breaker finds application in a wide range of industrial and commercial installations.

Key features and benefits

• Versatility: Can be used in circuits with a rated voltage from 230 to 500 V.
• Precise protection: Overload trip setting range (1.6 - 2.5 A) allows adaptation to specific application needs.
• High reliability: Thermal-magnetic construction ensures a quick and effective response to failures.
• Safety: The presence of a neutral conductor N increases user safety.
• Durability: Made of high-quality materials guaranteeing a long service life.
• Easy installation: Designed for mounting on a DIN rail, making installation easier and faster.
• Labeling: Has a window for describing the installation, which facilitates the identification of the circuit breaker's function in the event of a failure or maintenance.
• IP3X protection degree: Provides protection against access to live parts with a finger and against the ingress of solid objects larger than 2.5 mm.

The M250 circuit breaker is characterized by an overload trip setting range of 1.6 to 2.5 A and a rated continuous current of 2.5 A. The rated short-circuit capacity at 400 V AC is 6 kA. The device is adapted to work in circuits with a rated voltage from 230 to 500 V, and the short-circuit trip setting range is from 28 to 42 A. The connection of the main contacts is realized by a screw connection.

The M250 circuit breaker is a solid and reliable solution for professionals and end-users looking for effective protection of electric motors in their installations. Its compact dimensions (45 mm width, 72.5 mm depth and 89 mm height) allow for easy integration with existing electrical switchboards.
