Softstarter PSR16-600-11 / 7.5kW at 400V 1SFA896107R1100

Soft Starters – Smooth Start and Motor Protection

This compact soft starter PSR16-600-11, with a power of 7.5 kW at 400V, is a reliable solution for limiting motor inrush currents for three-phase motors. The device provides smooth start and stop, which translates to a longer motor life and reduced mechanical stress. The built-in bypass contactor minimizes energy losses and simplifies installation.

Functionality and Application

The PSR soft starter is an ideal solution for a wide range of applications, including pumps, fans, compressors and conveyors. Thanks to the ability to adjust the start-up parameters, it can be adapted to specific application requirements. The device is designed to operate in temperatures from -25°C to +40°C, making it suitable even in harsh environmental conditions. The ability to connect to a manual motor starter (MMS) allows for the construction of complete starting solutions with overload and short-circuit protection.

Key Features and Benefits

• Limitation of inrush currents: Reduces the load on the power supply network and extends motor life.
• Built-in bypass contactor: Reduces energy losses and simplifies installation – no additional components required.
• Wide supply voltage range: Ue 208…600 V AC – ensures compatibility with various installations.
• Low operating temperatures: Possibility of operation even at -25°C, which expands the range of applications.
• Simple configuration: Parameter adjustment using three potentiometers makes it easy to adapt the device to user needs.
• Versatility: Suitable for motors with a power of 7.5 kW at 400V and 4 kW at 230V (internal delta or standard connection).
• Protection: Protects the circuit against overload – just like standard circuit breakers in this class.
• Compact size: Allows installation in limited space.
