Softstarter PSR3-600-70 / 1.5kW at 400V 1SFA896103R7000

Compact motor starter – Softstart PSR3-600-70

This soft starter is an effective solution for smooth starting and stopping of electric motors, minimizing mechanical and electrical stress. The PSR series device is characterized by a compact design, making it easy to integrate even in limited spaces. It is an ideal choice for both installers and end-users looking for a reliable and easy-to-use solution.

Functionality and application

The PSR3-600-70 soft starter is designed for motors with a power of 1.5 kW at 400V and 0.75 kW at 230V. The rated operating current of the device is 3.9A. The built-in bypass contactor reduces energy losses and simplifies connections, and the adjustable starting characteristic allows you to adapt the operation to the specifics of the load. The device operates in a supply voltage range of 208 to 600V AC and a control voltage of 100-240V AC. The IP20 protection class provides basic protection against touch.

Advantages and benefits

• Compact size: Allows mounting in tight distribution spaces.
• Built-in bypass contactor: Reduces energy losses after the start-up is completed, increasing the energy efficiency of the installation.
• Adjustable starting parameters: Allows optimal adaptation to the load characteristics and minimizes inrush currents.
• Wide supply voltage range: Ensures compatibility with various electrical installations (208…600 V).
• Operation at low temperatures: Enables operation even down to -25°C, which is important in harsh environmental conditions.
• Simple installation and configuration: Thanks to three potentiometers, setting the parameters is quick and intuitive.
• Motor protection: Smooth starting reduces mechanical stress on the motor, extending its service life.
• Versatility: Suitable for applications with pumps, fans, conveyors and other devices requiring soft start.

Design and parameters

The PSR3-600-70 soft starter has been designed with ease of installation and maintenance in mind. Its design allows mounting on both DIN rail and directly on the mounting plate. The tripping class is adjustable, allowing precise adaptation to the application needs. The device has a protection class of IP20 and NEMA 1. Proper ventilation should be ensured during operation of the device, especially in closed spaces.
