Softstarter PSR9-600-11 / 4kW at 400V 1SFA896105R1100

Compact Soft Starters – Smooth Start and Motor Protection

This PSR9-600-11 soft starter is a compact device designed for smooth starting and stopping of three-phase motors. Using a soft starter reduces inrush currents during startup, which translates to reduced mechanical and electrical stress on the installation. The device is particularly useful in applications where frequent starting and stopping of the motor is standard, as well as where protection against overloads is required.

Construction and Application

The PSR9-600-11 soft starter is characterized by a compact design, which makes installation easier even in limited spaces. The built-in bypass contactor minimizes energy losses after the start-up process is completed, and also simplifies connections in the circuit. The device is designed to work with motors with a power of 4 kW at 400V and 2.2 kW at 230V. The rated operating current of the device is 9A. The ability to adjust parameters allows you to adapt the soft starter to the specific requirements of the application.

Advantages and Benefits

• Reduction of inrush currents: Smooth start minimizes inrush currents, protecting the motor, electrical installation and mechanical components from damage.
• Extended lifespan: Reducing mechanical stress translates to a longer lifespan of the motor and connected devices.
• Compact size: The compact design makes installation easier in tight switchgear spaces.
• Versatility: The ability to power with both AC and DC (24V) provides flexibility in the selection of the control source.
• Built-in bypass: Reduces energy losses after startup and simplifies electrical connections.
• Wide voltage range: Operation in a voltage range from 208 to 600V makes the device universal and can be used in various installations.
• Operation at low temperatures: The device maintains its operating properties even at temperatures down to -25°C, making it an ideal solution for outdoor or cold room applications.
• Protection class IP20: Provides basic protection against touching and ingress of solids, which is sufficient for most industrial and commercial applications.

Operating Parameters and Compliance with Standards

The PSR9-600-11 soft starter operates at an ambient temperature of up to 40°C and has a protection class of IP20 (NEMA 1). The device is adapted for mounting on a DIN rail or directly on a mounting plate using screws. The tripping class is adjustable, allowing for precise adjustment of the soft starter's operating characteristics to the needs of a specific application. The control voltage can be 24V AC/DC.
