Motor starter with thermal and electromagnetic trip unit with neutral conductor N M250 (2.5A - 4A) 606807

Motor starter – protection for motors and circuits

A motor starter with thermal and electromagnetic release is a reliable device used to protect electric motors from the effects of overloads and short circuits. Using this type of starter ensures the safety of the electrical installation and extends the life of connected devices. This model, catalog number 606807, is particularly useful in applications requiring protection against sudden current surges, such as starting motors with high inrush current.

Construction and functionality

The M250 starter is characterized by a solid construction in a housing providing full functionality. It has a built-in thermal release that reacts to long-term overloads, and an electromagnetic release that reacts instantly to short circuits. Additionally, the version with a neutral conductor N increases the safety and flexibility of the installation. The device is designed to operate in circuits with a rated voltage of 230 to 500 V and has a rated short-circuit breaking capacity of 6 kA at 400 V AC. The connection of the main contacts is made using a screw connection, which ensures a secure and durable connection of the wires.

Parameters and application

This starter is three-pole (3P) and has an overload release setting range of 2.5 to 4 A. The rated continuous current (Iu) is 4 A, and the short-circuit release setting range is 44.8 - 67.2 A. The rated operating power for AC-3 at 400 V is 7.5 kW, and at 230 V – 4.5 kW. Thanks to its compact dimensions (width 45 mm, height 89 mm, depth 72.5 mm) and IP3X protection class, the starter can be mounted in various environmental conditions. The description window for the installation allows for easy identification of the starter's function in a specific circuit – useful both during installation and subsequent maintenance or repair.
