Softstarter PSR30-600-70 / 15kW at 400V 1SFA896109R7000

Compact soft starters – smooth motor starting

This soft starter, model PSR30-600-70, is a compact device designed for the smooth starting of three-phase motors. Using a soft starter reduces inrush currents during startup, which translates to reduced load on the power supply network and extends the life of the motor and connected devices. This is particularly important in installations with limited connection power or where there are frequent motor starts and stops.

The device is characterized by a wide range of operating voltages (208…600V AC) and control voltages (100…240V AC), which ensures its versatility and ability to be used in different power systems. The built-in bypass contactor minimizes energy losses during motor operation at constant rotational speed. Additionally, the soft starter has a "RUN" signaling relay, indicating motor operation.

• Compact size: Allows mounting in tight switchgear spaces.
• Wide voltage range: Ensures compatibility with various power systems.
• Built-in bypass: Reduces energy losses and improves energy efficiency.
• RUN signaling relay: Enables remote monitoring of motor status.
• Operation in low temperatures: Guaranteed operation even down to -25°C, which is important in harsh environmental conditions.
• Easy installation: Possibility of mounting on a DIN rail or directly on a mounting plate facilitates installation and servicing.

Application and functionality

The PSR30-600-70 soft starter finds application in a wide spectrum of industrial and commercial applications where smooth motor starting is required. It is ideal for applications such as pumps, fans, compressors or conveyor belts. By limiting inrush currents, the soft starter protects the electrical network from overloads and prevents mechanical damage to the drive equipment.

The device allows for adjustment of the start and stop time, which enables optimization of the motor starting process according to the specific requirements of the application. The device's design is designed to ensure reliable operation in harsh industrial conditions – the IP20 degree of protection guarantees protection against accidental contact and against larger solid particles.

The PSR30-600-70 soft starter is characterized by a rated operating current of 30A, and its rated power for a three-phase motor is 15 kW at 400V and 7.5 kW at 230V. The control voltage is in the range of 100-240 V AC, the operating voltage is 208…600 V AC, and the degree of protection is IP20.
