Motor starter MS18-0.63A 004600343

Motor starter – reliable motor protection

The MS18-0.63A motor starter is a device designed to protect electric motors from overload and short circuit. It provides effective protection for motor power circuits, protecting them from damage and extending their lifespan. The thermomagnetic design combines the advantages of a thermal release (overload protection) and a short-circuit release (fast reaction to sudden current surges).

Functionality and application

The device is three-pole, which means it protects all three phases of the motor power supply. The rated continuous current of 0.63A makes the starter ideal for use in circuits with lower current draw. The use of phase failure sensitivity further increases the safety of the installation, reacting to voltage asymmetry and preventing damage to the motor caused by the loss of one phase. The rated operating power for AC-3 at 400V is 0.12 kW, and at 230V – 0.09 kW, allowing you to select the appropriate starter for a specific load.

Characteristics and benefits

• Thermal protection: The built-in thermal release protects the motor from overload, preventing overheating and damage to the windings.
• Short-circuit protection: A fast-reacting short-circuit release disconnects the circuit in the event of a short circuit, minimizing the risk of fire and serious failures.
• Phase failure sensitivity: Detects the loss of one of the supply phases and disconnects the circuit, protecting the motor from operating in incorrect conditions.
• Rated breaking capacity: The short-circuit breaking capacity at 400V AC is as high as 50 kA, which guarantees effective circuit interruption in the event of high short-circuit currents.
• Solid construction: The permanently mounted device is characterized by durability and reliable operation.
• Frame terminals: Allow easy and secure connection of power cables.
• Degree of protection IP20: Provides protection against touching with fingers and against the ingress of solid objects larger than 12.5 mm – standard for devices mounted in electrical cabinets.

The MS18-0.63A starter is an optimal solution for both professional installers and end-users looking for reliable protection for their electric motors. Its compact size makes it easy to install in tight spaces, and its high quality of workmanship guarantees long-lasting and trouble-free operation.
