Motor starter switch 2-pole Z-MS-0.63/2 248392

Motor starter – reliable motor protection

The Z-MS-0.63/2 motor starter is a compact device designed to protect electric motors from overload and short circuit. Its two-pole design makes it ideal for protecting circuits powering motors up to 0.18 kW. Thanks to the use of a thermal-magnetic trip unit, the starter effectively reacts to both long-term overloads and sudden current surges, ensuring the continuity of the installation and minimizing the risk of failure.

Functionality and application

The device is characterized by a wide adjustment range of the overload (0.4…0.63 A) and short-circuit (4.9…6.6 A) trip units, allowing for precise adaptation to the characteristics of the protected circuit. The starter with a control lever is easy to operate and allows for quick disconnection of the circuit in the event of a failure. The use of screw connections ensures a secure and durable connection of the wires. The IP20 degree of protection guarantees protection against accidental contact, increasing safety of use.

• Motor protection: Protects electric motors from the effects of overloads and short circuits, extending their lifespan.
• Precise adjustment: The adjustment range of the trip units allows adaptation to specific application needs.
• Fast reaction: The thermal-magnetic trip unit ensures quick disconnection of the circuit in the event of a failure.
• Safety of use: IP20 protection degree protects against accidental contact.
• Durable connections: Screw connections guarantee a secure and stable connection of the power supply wires.

Technical characteristics and construction

The Z-MS-0.63/2 starter has been designed with reliability and durability in mind. The complete device in the housing is made of high-quality materials, resistant to mechanical damage and environmental conditions. The rated continuous current of 0.63 A and the rated short-circuit breaking capacity of 10 kA at 400 V AC confirm its high performance and effectiveness. The device is designed to operate in circuits with a rated voltage of 400 V AC, and its compact dimensions (75 mm height, 36 mm width and 80 mm depth) facilitate installation even in tight spaces. Lack of phase failure sensitivity means it does not react to voltage asymmetry in a three-phase network – this is important in some industrial applications.
