Motor starter with thermal and electromagnetic trip release, possibility to connect N conductor M-611 N (4A - 6.3A) 6112-370001

Motor starter M-611 N is a reliable protection for electric motors, designed for both professional and domestic applications. The device combines thermal and electromagnetic overload functions, providing comprehensive protection against overload and short circuit. The possibility of connecting the N wire increases its functionality and simplifies installation.

Characteristics and application

The switches from the M-611 series are characterized by a solid construction and high quality of workmanship, which guarantees long-lasting and trouble-free operation. The thermal-magnetic tripping method ensures an effective response to various types of threats, protecting the motor and electrical installation. The rated power for AC-3 is 7.5 kW at 400 V and 4.5 kW at 230 V, making it a suitable choice for a wide range of applications. Use in industry, workshops or homes - everywhere where reliable motor protection is required.

Construction and parameters

The device has three poles and is designed to operate at a rated voltage of 400 V. The rated continuous current (Iu) is 6.3 A, and the setting range of the overload release is 4…6.3 A. The rated short-circuit breaking capacity (Icu) at 400 V AC is 1.25 kA. The switch is made as a complete device in a housing, which facilitates assembly and provides additional protection for internal components. The connection of the main contacts is made using a screw connection - a proven method ensuring a secure and durable connection of the wires. The dimensions of the device are 75 mm high, 60 mm wide and 105 mm deep, and the degree of protection IP20 provides basic protection against touching and ingress of solid objects.
