Motor starter switch 3-pole Z-MS-6.3/3 248410

Three-phase motor switch – reliable protection for your motors

This three-pole motor switch Z-MS-6.3/3 from Eaton is a key element in protecting the electrical installation powering motors. The device effectively protects motors from overload, short circuit and potential damage resulting from malfunction. This ensures not only operational safety, but also extends the life of connected devices.

The switch is designed for easy mounting on a standard 35 mm rail (DIN EN 50022) and intuitive operation. Solid construction and high mechanical and electrical strength guarantee long-lasting and trouble-free operation in demanding conditions. The built-in status indicator (red/green) facilitates quick identification of any problems.

Functionality and technical parameters

The Z-MS-6.3/3 switch is a complete device in a housing, ready for immediate use. Its operation is based on the principle of magnetic tripping, which ensures a quick response in the event of a short circuit. Thermal protection protects against the effects of overloads, and the setting range of the overload release allows adaptation to specific application needs – this range is from 4 to 6.3 A. The rated continuous current of 6.3 A and the rated operating power for AC-3 at 400 V of 2.2 kW make the switch ideal for protecting medium-power motors. It has a rated short-circuit breaking capacity Icu at 400 V AC equal to 10 kA, and the connection of the main contacts is realized by a screw connection. The degree of protection is IP20, which provides protection against finger contact and solid bodies, and the rated operating voltage is 400 V. The device has a complete device structure in a housing, ready for mounting.

The switch is characterized by precise adaptation to the load characteristics thanks to the setting range of the overload release and high resistance to short-circuit currents ensured by the rated short-circuit breaking capacity. Reliable and durable electrical connections are guaranteed by the screw connection of the main contacts, and protection against finger contact and solid bodies is ensured by the IP20 degree of protection. The device is adapted to the standard voltage of a three-phase network – the rated operating voltage is 400 V – and is ready for mounting thanks to the complete device structure in a housing.

Applications and benefits

The Z-MS-6.3/3 motor switch finds wide application in various industries as well as in residential and commercial construction. It will be useful wherever reliable protection of electric motors against overloads and short circuits is required. Thanks to its versatility and ease of installation, it is an ideal solution for both professional installers and end users. By choosing this switch, you invest in the safety and long-term operation of your electrical devices.
