Softstarter PSR30-600-11 / 15kW at 400V 1SFA896109R1100

Soft Starters – Smooth Start and Motor Protection

The compact PSR30-600-11 soft starter is a solution designed for smooth starting and stopping of three-phase motors. The device limits inrush currents, reducing the mechanical and electrical stress on the motor and the power supply network. This extends the motor's lifespan and improves the reliability of the entire system. The built-in bypass contactor minimizes energy losses after the start-up phase, and easy configuration using three potentiometers significantly simplifies the commissioning process.

The PSR soft starter is ideal for both installers and end-users. Installers will appreciate the simplicity of installation and configuration, while users will benefit from reliable operation and motor protection. The device is suitable for various industrial applications, such as pumps, fans, compressors, and conveyors. The ability to operate in temperatures down to -25°C makes it suitable for use in harsh environmental conditions.

Design features and functionality

The PSR30-600-11 soft starter offers a wide range of operating voltages (208...600 V AC) and control voltages (24 V AC/DC), ensuring compatibility with various installations. Smooth start with adjustable ramp voltage and smooth stop minimize mechanical shocks, protecting the motor from damage. The built-in bypass contactor effectively reduces energy losses during operation at constant speed. Additionally, the device has RUN and TOR (Top of Ramp) output signals allowing monitoring of the motor's operating status.

The device is characterized by a rated operating current of 30 A, operates in a voltage range of 208 to 600 V AC and allows controlling motors with a power of up to 15 kW at 400V. The control voltage is 24 V AC/DC, and the degree of protection is IP20. The soft starter operates as a unidirectional circuit.

The device complies with IEC standards and has safety certificates, guaranteeing its reliable operation in demanding industrial conditions. The possibility of connecting to the ABB MMS motor manual starter facilitates the construction of complete starting solutions with full protection against overload and short circuit. Additionally, the functionality of the soft starter can be optionally extended with Fieldbus communication using an external adapter.
