• Integrated motor overload protection enhances operational safety
• Fault memory functionality stores up to 10 faults for analysis
• Equipped with internal bypass contacts for reduced energy loss
• Underload monitoring helps to prevent equipment damage
• Modbus RTU Interface allows easy integration with control systems
• Designed to suppress closing transients for motor protection

• Used for reliable soft starting of industrial motors
• Commonly applied in pump and fan systems for gradual acceleration
• Ideal for operations requiring consistent power management
• Utilised in environments with high starting torque requirements

The internal bypass function allows current to flow directly across the starter once the motor is running, effectively reducing energy loss compared to traditional starters, thus improving overall energy efficiency during operation.

It operates within a voltage range of 200 to 690 V AC, accommodating diverse electrical systems and ensuring compatibility across various applications.

The fault memory feature allows users to track and analyse the last 10 faults, facilitating quick troubleshooting and optimising maintenance schedules, thereby minimising downtime.

By gradually increasing the voltage to the motor during start-up, this function reduces stress on the motor, which helps to extend its lifespan and minimise maintenance frequency.
