Softstarter PSR45-600-70 / 22kW at 400V 1SFA896111R7000

Compact softstarter PSR45-600-70 – smooth start and motor protection.

The PSR45-600-70 softstarter is an advanced device designed for the controlled start-up of three-phase motors. Its compact design allows for easy integration with existing installations, and the built-in bypass contactor minimizes energy losses after the start-up is complete. The device is ideal for both professional installers and end-users looking for a reliable solution to limit inrush currents and extend motor life.

Application and functionality

The PSR45-600-70 softstarter finds application in a wide range of industrial and commercial applications where smooth motor start-up, reduction of mechanical stress and protection against overloads are required. Thanks to the adjustable ramp-up and ramp-down time, it is possible to adapt the start-up parameters to the specific needs of a given application. The device also provides remote control and monitoring of the motor's operating status.

Key features and benefits

• Wide voltage range: Ability to operate in networks with a voltage of 208 to 600 V AC, ensuring compatibility with various power systems.
• Built-in bypass contactor: Reduces energy losses after the start-up is complete, improving the energy efficiency of the installation.
• Compact dimensions: Allow for mounting in tight spaces, which is particularly important in modernized installations.
• Adjustable start-up parameters: Allows for optimal adaptation of the start-up characteristics to the type of load and application requirements.
• Reliability and durability: Made of high-quality components guarantees long device life and trouble-free operation.
• Operation at low temperatures: Enables operation even at -25°C, which is important in harsh environmental conditions.
• Universal control voltage: Supports control voltage of 100-240 V AC (or 24V DC in other versions), which facilitates integration with existing control systems.

Technical specifications and operating parameters

The device is designed to work with three-phase motors with a power of up to 22 kW at 400 V or 11 kW at 230 V. The rated operating current is 45 A at an ambient temperature of 40°C. The IP10 protection class provides basic protection against touch and ingress of solid objects. The release class is adjustable, allowing for precise adaptation of the release characteristics to the needs of the application. Remember to use the recommended overload protection MS450 (36-45A).
