Motor starter switch 3-pole Z-MS-4.0/3 248409

Three-phase motor starter – reliable motor protection

This three-pole motor starter Z-MS-4.0/3 from Eaton is a key element in protecting the electrical installation powering motors. It provides comprehensive protection against overload and short circuit, and also allows for manual control of the motor. The device is designed for mounting on a standard 35 mm rail and is characterized by ease of use and high reliability.

Functionality and application

The Z-MS-4.0/3 starter is designed to protect three-phase motors with a power of up to 1.5 kW. Its overload release setting range (2.5…4 A) allows for precise adjustment to the load characteristics. Quick mounting on a DIN EN 50022 rail and intuitive operation make it an ideal solution for both professional installers and end users. The starter finds application in residential construction as well as in various industrial applications.

Key features and benefits

• Thermal and short-circuit protection: Protects the motor from damage due to overload or short circuit in the circuit.
• Setting range: The ability to adjust the tripping current in the range of 2.5 - 4 A allows adaptation to a specific motor and application.
• High short-circuit breaking capacity: Rated short-circuit breaking capacity Icu at 400 V, AC is 10 kA, which ensures effective disconnection of the circuit in the event of a short circuit.
• Simple installation: Mounting on a standard 35 mm rail using clips facilitates and speeds up installation.
• Status indicator: Built-in operating indicator (red/green) allows for quick visual assessment of the starter status.
• Durable construction: Made of high-quality materials ensures long life and reliable operation.
• Screw connection: Provides a secure and durable connection of wires.
• Device construction: Complete device in a housing – ready for mounting and use immediately after unpacking.

Using this starter translates into increased motor operating safety and reduced risk of costly failures. Thanks to the precise setting of the tripping current, unnecessary tripping of the device during normal operation can be avoided, while ensuring effective protection in emergency situations.
