Motor starter switch 2-pole Z-MS-6.3/2 248397

Motor starter Z-MS-6.3/2 is a reliable protection for electric motors, designed for both professional and domestic applications. The device effectively protects circuits against overload and short circuit, ensuring safe and stable operation of connected devices.

Characteristics and application

This starter, with an overload release setting range of 4…6.3 A, is ideal for protecting motors up to 2.2 kW at 400 V AC. The construction based on a magnetic release guarantees a quick response in the event of a short circuit, and thermal protection prevents damage caused by overload. This makes the starter suitable for a variety of applications – from simple household appliances to more demanding industrial installations. DIN rail mounting simplifies integration with existing electrical systems.

Construction and features

The Z-MS-6.3/2 starter is a complete device in a housing, ready for mounting. It has two poles and provides a rated continuous current of 6.3 A. The connection of the main contacts is made using screw connections – a solution appreciated by installers for its reliability and ease of installation. The degree of protection IP20 means protection against finger contact and against the ingress of solid objects larger than 12.5 mm, which is sufficient for most standard indoor applications.

• Fast response: Magnetic release provides instant protection against short circuits.
• Thermal protection: Prevents damage to the motor caused by overload.
• Easy installation: DIN rail mounting design simplifies installation.
• Reliable connections: Screw terminals guarantee stable and secure electrical connections.
• Rated breaking capacity: Short-circuit breaking capacity at 400 V AC is 10 kA – an important parameter for ensuring installation safety.
• Compact dimensions: Height 75 mm, width 36 mm and depth 80 mm allow installation in limited space.
• Short-circuit setting range: Adjustment in the range of 63…82 A allows you to adjust the sensitivity of the starter to the specifics of the protected installation.

The device is designed to operate at temperatures from -25°C to +50°C, making it a universal solution for various environmental conditions. Lack of phase failure sensitivity means that the starter does not react to the loss of one of the supply phases – which may be important in some industrial applications (however, it should be remembered to use additional protection in the event of voltage asymmetry).
