ABB PSR37-600-70 Soft Starter 37A

The ABB PSR37-600-70 Soft Starter is an advanced solution for protecting and extending the lifespan of electric motors by reducing electrical stress during start-up and stop. This progressive starter is designed to optimise starting currents, minimising the impact on the motor, thereby increasing its durability and reliability. With a rated current of 37 A and an operating voltage of 208-600V, this model is suitable for three-phase motors up to 18.5 kW (400 V) or 22 kW (500 V).

The installation and use of the PSR37 are straightforward, saving time during assembly and commissioning. The starter includes an internal bypass contact and is compatible with recommended overload protection, providing a compact and complete solution in a single unit.

Main Features:

• Rated current of 37 A and power up to 18.5 kW: Suitable for three-phase motors in industrial applications, this starter is ideal for motors of 7.5 kW at 230 V, 18.5 kW at 400 V and 22 kW at 500 V.
• Smooth start and stop: The PSR37 includes soft start with voltage ramp and soft stop functions, reducing wear on mechanical and electrical components.
• Integrated protection: This starter includes recommended overload protection (MS450 28-40), ensuring safe and efficient motor operation.

Additional Benefits:

• Easy installation and use: The starter is designed to be intuitive, with screw terminals and a compact structure, facilitating assembly and connection. Additionally, the indicator LEDs allow system status to be viewed at all times.
