• Motor starting: Enables safe starting of electric motors with a power of up to 9 kW at 400 V AC and 5.5 kW at 230 V AC.
• Phase failure control: Increases work safety, protecting the motor from damage in the event of a missing phase.
• Fixed mounting: The device is designed for fixed mounting, ensuring stability and reliability of connections.
• Frame terminals: Allow easy and secure connection of wires.
• Rated short-circuit breaking capacity: 12.5 kA at 400 V AC provides effective disconnection of the circuit in the event of a short circuit.

Construction and parameters

The MS18-18A starter is characterized by a solid construction and high quality workmanship. The housing with a protection degree of IP20 provides protection against touch and contamination, but requires installation in dry rooms. The setting range of the overload release (13-18 A) allows precise adjustment to the load characteristics. The starter does not have an integrated auxiliary contact or undervoltage release, which affects its compact size and ease of use. This makes it an ideal solution for both professional installers and end-users looking for reliable protection of their devices.
