Motor starter 3-pole Z-MS-0.63/3 248405

Motor protection switch – reliable motor protection

The Z-MS-0.63/3 motor protection switch is a three-pole device designed to protect electric motors from overload and short circuit. The design based on a thermal-magnetic release ensures effective protection of the installation, and the ability to adjust the setting current allows adaptation to specific application needs. This is a solid solution for both professionals and end-users who value safety and reliability.

Functionality and application

The device is characterized by a screw connection of the main contacts, which facilitates installation and connection in the installation. The rated continuous current at 0.63A and the overload release setting range of 0.4…0.63A make the switch ideal for protecting motors with a power of up to 0.18 kW (at 400V). Use in circuits with characteristic C allows for a slower response to short current surges, therefore it tolerates starting devices with a motor well. The switch finds application in various industrial and domestic applications where protection of electric motors against damage caused by overload or short circuit is required.

Key features and benefits

• Thermal protection: Built-in thermal protection protects the motor from overheating, which extends its life and minimizes the risk of failure.
• High short-circuit breaking capacity: Rated short-circuit breaking capacity at 10kA at 400V AC guarantees effective disconnection of the circuit in the event of a short circuit, protecting both the motor and the remaining elements of the installation.
• Setting current adjustment: The ability to precisely set the overload release range (0.4…0.63A) allows for adapting the protection to the specific requirements of a given motor.
• Solid construction: Complete device in housing provides durability and resistance to mechanical damage and external factors (IP20 protection degree).
• Simple installation: Screw connection of the main contacts facilitates quick and easy installation in the existing electrical installation.
• Safety: Magnetic tripping method ensures a quick response in the event of a short circuit, minimizing the risk of equipment damage and hazards to users.
