Schneider Electric ATS01 soft starter module, 110–480 V input, 47.5–63 Hz, IP20, 45 mm width

Schneider Electric ATS01 soft starter module is a compact motor starting device designed to reduce mechanical stress and electrical peaks during motor start-up. The unit accepts a wide input voltage range of 110–480 V and operates within a frequency band of 47.5–63 Hz. With a slim 45 mm width and IP20 protection, this soft starter is intended for installation where space is limited and basic enclosure protection is required.

Advantages

The ATS01 soft starter provides controlled voltage ramp-up to limit inrush current and soften torque at motor start, helping to extend the life of mechanical components and reduce electrical disturbances on the supply network. Its compact dimensions and modular form factor simplify panel integration. The device’s operational frequency range and broad input voltage acceptance make it compatible with a variety of industrial and commercial motor systems.

Suitable for

• Starting three-phase induction motors in industrial machinery
• Pumps and fans where reduced mechanical shock is required
• Conveyors and belt drives to limit initial torque
• Retrofit installations with limited panel space

How to use

Mount the ATS01 module on a suitable DIN rail or panel area that accommodates its 45 mm width and ensure adequate ventilation around the IP20-protected enclosure. Connect the incoming supply and motor connections following Schneider Electric wiring recommendations and local electrical codes. Configure the starter settings according to motor nameplate values and the application’s required ramp times to achieve the desired soft-start behavior. Verify connections and perform a controlled test start to confirm correct operation before placing the motor into normal service.

Usage recommendations

Use the ATS01 soft starter in installations with appropriate overload and short-circuit protection upstream. Avoid exposure to environments requiring higher ingress protection than IP20 and ensure that ambient temperature and ventilation meet the manufacturer’s guidelines. For motors with specific control requirements or where full electronic protection is needed, combine the soft starter with additional motor protection devices and consult technical documentation for parameter settings.
