Softstarter PSR60-600-70 / 30kW a 400V 1SFA896112R7000

Soft starters – smooth start and motor protection

This soft starter, from the PSR family, is a compact device designed for smooth starting and stopping of three-phase motors. Its main function is to limit electrical and mechanical loads during start-up, which translates to a longer motor life and the entire installation. The device is particularly useful in applications where frequent starts or high torque occur.

Application and functionality

The PSR soft starter is an ideal solution for both professional installers and end-users looking for reliable motor protection. The built-in bypass contactor ensures continuous operation after the start-up phase is completed, minimizing energy losses. The device is dedicated to working with motors up to 30 kW at 400V and 15 kW at 230V. The tripping class is adjustable, allowing you to adapt the operating parameters to the specifics of a given motor and load.

Construction and mounting

The compact dimensions of the device allow for mounting in limited spaces, both on a DIN rail and on a mounting plate. The control voltage can be set to a range of 100-240V AC, ensuring compatibility with various control systems. The IP10 degree of protection guarantees basic protection against touching and the ingress of solid objects. It is important to remember the ambient temperature – the device is adapted to operate at a temperature of up to 40°C, as well as in conditions of negative temperatures (down to -25°C).

Key features:

• Voltage versatility: Operation in the voltage range from 208 to 600 V allows for use in different power networks.
• Built-in bypass: Ensures a smooth switch to rated operation after start-up, minimizing energy losses and extending the life of the device.
• Adjustable tripping class: Allows precise adjustment of operating parameters to the characteristics of the load and motor.
• Compact dimensions: Make it easy to mount even in tight spaces.
• Wide power range: Supports motors up to 30 kW (at 400V) and 15 kW (at 230V).
• Adaptation to low temperatures: Possibility of operation even at -25°C.
• Rated current: The device operates with a rated current of 60A at an ambient temperature of 40°C.
