Softstarter PSR12-600-70 / 5.5kW at 400V 1SFA896106R7000

Softstart – smooth engine start, protection and savings

This soft starter, model PSR12-600-70, is a compact device designed for smooth starting of three-phase motors. Using a soft starter reduces inrush currents during startup, which translates to lower load on the power supply network and extends the life of the motor and connected devices. This is an ideal solution for both professional installers and end-users looking for a reliable way to optimize engine performance.

Functionality and application

The PSR12-600-70 soft starter is particularly useful in applications where frequent starting and stopping of motors generates high mechanical and electrical loads. The device offers adjustable starting characteristics, allowing you to tailor its operation to the specific needs of a given installation. The built-in bypass contactor ensures efficient heat dissipation and allows for continuous operation of the device without the risk of overheating. This makes the soft starter suitable for demanding industrial conditions.

AC power supply with a voltage from 208 to 600V and the ability to control a voltage of 100-240V AC make the device universal and can be used in various power systems. The IP20 protection class provides basic protection against touch and contamination. Additionally, PSR soft starters are known for their ability to operate at low temperatures – even down to -25°C – making them suitable for outdoor or cold room applications.

Key advantages

• Reduction of inrush currents: Smooth start minimizes load on the power supply network and extends engine life.
• Built-in bypass contactor: Ensures efficient heat dissipation and allows for continuous operation of the device.
• Wide voltage range: Compatibility with various power systems (208-600V AC).
• Adjustable starting characteristics: Ability to adapt the operation to specific installation needs.
• Operation at low temperatures: Possibility of use in difficult environmental conditions (down to -25°C).
• Compact dimensions: Facilitate mounting even in limited spaces.
• Reliability of the ABB brand: Guarantee of high quality and long-term operation.

Operating parameters and installation

The PSR12-600-70 soft starter is designed to work with motors with a power of 5.5 kW at 400V and 3 kW at 230V. The rated operating current of the device is 12A at an ambient temperature of 40°C. Mounting is done on a DIN rail or with screws on a mounting plate, which provides installation flexibility. The tripping class is adjustable, allowing precise tuning of the device's operating parameters to specific application requirements. The IP20 protection class provides basic protection against touch and contamination, but remember to locate the device in a dry and well-ventilated place.
