Motor starter with thermal and electromagnetic trip unit with neutral conductor N M250 (14A - 20A) 606811

Electric motor protection – reliable M250 circuit breaker

This three-pole M250 motor circuit breaker with thermal and electromagnetic trip unit is a key element in protecting electrical installations powering motors. It provides comprehensive protection against the effects of overloads and short circuits, minimizing the risk of damage and downtime. Equipped with a neutral conductor N, it is ideal for applications where full circuit protection is required.

This circuit breaker, with a rated current of 20A, effectively protects motors up to 7.5 kW at 400V and 4.5 kW at 230V. The short-circuit breaking capacity of 3kA at 400V AC guarantees a quick response in the event of a failure. The device's design, based on the thermomagnetic principle, ensures precise and reliable operation in various operating conditions.

Mounting and application:

The M250 circuit breaker is designed for mounting on a TH-35 DIN rail in standard modular distribution boards. Its compact dimensions (45 mm wide, 89 mm high and 72.5 mm deep) allow for easy integration with existing infrastructure. Equipped with screw connections for the main contacts, it provides secure and durable electrical connections. A window on the housing allows for clear labeling of the circuit, making it easier to identify and service the installation.

Design features and benefits:

• Thermal protection: The thermal trip unit with adjustment in the range of 14-20A protects the motor against overloads, preventing overheating of the windings and extending its service life.
• Short-circuit protection: The electromagnetic trip unit with a setting range of 224-336A reacts immediately to a short circuit, disconnecting the circuit and minimizing potential damage to equipment and fire hazard.
• Neutral conductor N: The presence of a neutral conductor N ensures full circuit protection and improves safety.
• High reliability: The solid construction of the device and the use of high-quality materials guarantee long-lasting and trouble-free operation in demanding industrial and domestic conditions.
• Protection class IP3X: Provides protection against touching live conductive parts and against the ingress of solid objects with a diameter greater than 2.5 mm – important for safety.
• Thermomagnetic tripping method: The combination of thermal and short-circuit protection provides comprehensive protection of the motor against various types of failures.
• Designed to operate in the voltage range of 230-500V: Enables wide application in various electrical installations.

The M250 circuit breaker is an investment in the safety and reliability of your electrical installation – for both professionals and end users.
