Motor starter with thermal and electromagnetic trip release, possibility to connect N conductor M-611 N (6.3A - 10A) 6112-420001

Motor starter M-611 N is a reliable protection for electric motors, designed for both professional and home use. The device combines the functions of a thermal and electromagnetic overload relay, providing comprehensive protection against overloads and short circuits. The possibility of connecting the N conductor further increases its functionality and simplifies installation in various systems.

Protection and functionality

This three-pole switch (number of poles: 3) is designed to operate in circuits with a rated voltage of 400 V, AC. The rated continuous current of 10 A and the short-circuit capacity of 1.25 kA at 400 V, AC guarantee effective protection of the electrical installation and connected devices. Equipped with an adjustable thermal release in the range of 6.3 - 10 A, it allows for precise adjustment to the load characteristics. Additionally, a short-circuit release with a value of 170 A ensures a quick response in the event of a dangerous short circuit. The tripping method - thermal-magnetic - is a proven method ensuring reliable operation of the device.

Construction and mounting

The M-611 N circuit breaker is a complete device in a housing, ready for installation. Compact dimensions (height: 75 mm, width: 60 mm, depth: 105 mm) allow for easy installation even in limited spaces. Connection of the main contacts is made using screw connection, which ensures a secure and durable connection of the wires. The degree of protection IP20 protects against finger contact and the ingress of solid objects larger than 12.5 mm - important for safe use.

Applications and benefits

• Versatility: ideal for protecting electric motors in various industrial and home applications.
• Overload protection: the thermal release protects the motor from damage caused by prolonged overload. Characteristic C allows it to react more slowly to short current surges, therefore it tolerates starting motors well.
• Short-circuit protection: the electromagnetic release instantly disconnects the circuit in the event of a short circuit, minimizing the risk of damage to the installation and fire.
• Possibility of connecting the N conductor: simplifies installation and integration with existing electrical installations.
• Durability: high quality of workmanship guarantees long and trouble-free operation of the device.
• Compliance with standards: meets the required safety standards, ensuring safe use (IP20).
• Efficiency: the rated operating power for AC-3 is 7.5 kW at 400 V and 4.5 kW at 230 V, which allows for effective protection of motors of various power.

This circuit breaker is a solid choice for any installer and user looking for reliable motor protection - both in newly built installations and during the modernization of existing power systems.
