Motor starter with thermal and electromagnetic trip release, possibility to connect N conductor M-611 N (2.5A - 4A) 6112-330001

Motor starter M-611 N is a reliable device designed to protect electric motors from overload and short circuit. The use of a thermal and electromagnetic release ensures comprehensive protection, and the ability to connect the N wire increases installation flexibility. This three-pole switch, with a rated continuous current of 4A, is an ideal solution for both professional installers and end-users looking for safe and effective motor protection.

Characteristics and application

Switches from the Legrand M-611 series are components used for connecting, protecting and disconnecting electrical circuits powering motors. The device's design allows for effective protection against the effects of blocked starting, overload and short circuit. In addition, the built-in thermal release protects the motor winding from overheating, and the electromagnetic release reacts immediately to sudden current surges. The ability to connect the N wire facilitates installation and integration with existing electrical infrastructure. The device finds application in a wide range of industrial, commercial and domestic installations where protection of electric motors is required.

Construction and parameters

The M-611 N switch is characterized by a solid construction in a housing providing an appropriate degree of protection IP20. The connection of the main contacts is made using screw connections, which guarantees a stable and secure connection of the wires. The rated operating voltage is 400 V AC, and the rated short-circuit breaking capacity at 400 V AC is 1.25 kA. The device is designed to operate at temperatures from -25°C to +50°C. The rated power for AC-3 at 400 V is 7.5 kW, and at 230 V – 4.5 kW. It is worth noting the setting range of the overload release, which is 2.5 – 4 A, and the setting range of the short-circuit release, which is fixed at 68 A. This switch is designed for use category AC-3 and can perform up to 60 switching cycles per hour.
