Softstart PSR37-600-70 / 18,5kW a 400V 1SFA896110R7000

Soft starters – smooth start and motor protection

The PSR37-600-70 soft starter is a compact solution for controlling three-phase motors, designed to limit electrical and mechanical loads during start-up. The device allows for smooth starting and stopping of the motor, which translates to extended motor life and reduced risk of failure. This is an ideal solution for both installers and end-users looking for a reliable and efficient motor starting system.

Construction and application

The PSR37-600-70 soft starter is designed to work with motors up to 18.5 kW at 400V and 7.5 kW at 230V. The built-in bypass contactor ensures continuous operation after the start-up phase is completed, minimizing power losses and preventing the device from overheating. The possibility of mounting on a DIN rail or directly on a mounting plate facilitates installation in various conditions. The device is adapted to operate in a temperature range from -25°C to 60°C, making it suitable even in harsh industrial conditions.

Key features and benefits

• Wide voltage range: The ability to power from a network with a voltage of 208 to 600V AC makes the device universal and can be used in various installations.
• Compact dimensions: It takes up little space, which is especially important in applications with limited mounting space.
• Built-in bypass contactor: Ensures reliable operation and minimizes energy losses after the start-up phase is completed.
• Adjustable tripping class: Allows you to adapt the device's operating characteristics to the specific requirements of the application.
• Universal control voltage: The ability to choose the control voltage AC (100-240V) increases installation flexibility.
• Operation in harsh conditions: The operating temperature range from -25°C to 60°C guarantees reliable operation even in demanding industrial environments.
• Motor protection: Although it does not have a built-in motor overload protection, its operation contributes to reducing mechanical stress during start-up, which indirectly affects the motor life.
• Simple installation: The possibility of mounting on a DIN rail or directly on a mounting plate facilitates and speeds up installation.

The PSR37-600-70 soft starter is a solid and reliable device that provides smooth starting of asynchronous motors, protecting them from mechanical and electrical damage and extending their life. It is an investment that translates into energy savings and reduced maintenance costs.
