Softstarter PSR45-600-11 / 22kW at 400V 1SFA896111R1100

Softstart – smooth start, longer engine life

This softstarter, designated PSR45-600-11, is a compact device used for smooth starting and stopping of three-phase motors. Its task is to limit inrush currents during startup, which translates to reduced load on the power supply network and extended life of the motor itself and the devices connected to it. The device is particularly useful in applications where frequent starting and stopping of the motor is the norm – for example, in pumps, fans or conveyors.

Versatility and scope of applications

The PSR45-600-11 softstarter is distinguished by a wide range of supply voltages (208…600 V AC) and the ability to work with both AC and DC control voltage (24V). This allows for its flexible use in various electrical installations. The rated motor power it can handle is 22 kW at 400V and 11 kW at 230V. The rated current of the device is 45A at an ambient temperature of 40°C. The built-in bypass simplifies installation and ensures reliable operation.

Benefits for the installer and user

• Reduction of mechanical loads: Smooth start minimizes mechanical shocks in gearboxes and couplings, which extends their life.
• Protection of the power supply network: Limiting inrush currents prevents voltage drops in the network and disturbances in the operation of other devices.
• Simple installation: The built-in bypass simplifies installation and allows for easy bypassing of the softstarter in case of failure or the need for direct motor start.
• Parameter adjustment: The ability to adjust the start and stop time allows you to adapt the device's operation to the specifics of a given application.
• Wide voltage range: Compatibility with different supply voltages (208…600 V AC) increases the versatility of the device.
• Operation in harsh conditions: The device can operate at temperatures up to 40°C, making it suitable for industrial applications.
• Compact dimensions: Allow for mounting in tight spaces.
• Unidirectional function: Provides basic functionality of smooth start without additional complications.

The PSR45-600-11 softstarter is a solid solution for professionals looking for a reliable device to control the start of three-phase motors, which will provide protection for both the motor and the entire electrical installation. Additionally, the ability to operate in temperatures even below zero st. C (-25 st. C) expands its range of applications.
