Softstart PSE30-600-70 1SFA897103R7000

Motor Soft Starter – PSE30-600-70

This softstarter, catalog number 1SFA897103R7000, is an advanced device designed for smooth starting and stopping of three-phase motors. Its main function is to limit inrush currents, which translates to reduced load on the power supply network and extended motor and connected device life. This is particularly important in applications where frequent motor starting and stopping generates high current surges.

Construction and functionality

The PSE30-600-70 features a built-in bypass contactor, which takes over the full motor load after the starting process is complete, minimizing energy losses on the softstarter elements. It also has a built-in motor overload protection, providing an additional level of protection against damage. It is equipped with a clear display, making configuration and monitoring of operating parameters easier. Control is via an AC signal with a voltage of 100-250V.

Application and benefits

The device finds wide application in industry, where torque control during motor start-up is required. It is ideally suited for applications such as pumps, fans, compressors or conveyor belts. Thanks to torque control, it is possible to adapt the starting characteristics to the specifics of a given device and load. Using the PSE30-600-70 softstarter translates to:

• Reduction of inrush currents: Limiting the starting current minimizes the load on the power supply network and prevents voltage drops.

• Extended motor life: Smooth starting reduces mechanical stress on the motor and connected elements, resulting in a longer life.

• Protection against overloads: Built-in overload protection protects the motor from damage caused by excessive load.

• Optimization of operating costs: Reducing energy losses and extending the life of equipment translates to lower operating costs.

• Easy configuration: The display makes it easy to set the softstarter operating parameters according to the application requirements.

Operating parameters

The PSE30-600-70 softstarter is designed to operate in a wide range of supply voltages (208…600 V) and ambient temperatures (up to 40°C). The rated power of a three-phase motor with a standard connection (400 V) is 15 kW, and with a star connection – 11 kW. The rated operating current of the device is 30 A. The device has an adjustable release class, allowing precise adjustment of parameters to specific application needs. The IP00 protection class means there is no protection against the ingress of solids and water – the device is intended for mounting in enclosures or electrical cabinets.
