Dold 2 Phase Soft Start Motor Starter 400V AC 5.5 kW IP30

Dold IR9027 AC400V 5.5kW 2 Phase Soft Start Motor Starter is a high-quality device designed for smooth starting of three-phase asynchronous motors. Operating at 400V AC with a power rating of 5.5 kW and two-phase control, this soft starter minimizes mechanical shocks and electrical stress during motor startup. The IP30 enclosure rating provides protection suitable for industrial environments.

Its compact design with overall dimensions of 105 mm length, 90 mm width, and 59 mm depth enables easy mounting on standard 35 mm DIN rails. The device operates reliably up to a maximum temperature of 60°C and complies with CE and EC/EN 60947-4-2 standards, ensuring safety and quality.

The IR9027 Soft Starter uses phase control to steadily increase current in two motor phases, ensuring smooth torque build-up and preventing damage due to abrupt starts. This characteristic reduces starting noise and avoids slippage or tipping of conveyed items, making it ideal for conveyor belts, fans, pumps, compressors, packaging machines, and door operating mechanisms.

After successful motor startup, an internal relay bridges the power semiconductor to reduce power losses. Starting time and torque can be adjusted independently, and the device can be combined with motor brake units. LED indicators provide clear operational feedback during use.

The product requires a clockwise rotating field and must not be used with capacitive loads such as reactive power compensation. It is designed to enhance the lifespan of asynchronous motors and mechanical components through gentle starting.

This motor starter is manufactured in Germany, reflecting high manufacturing standards and quality assurance. Designed for two-phase smooth motor start-up control. Power rating suitable for up to 5.5 kW motors. IP30 rated enclosure for protection in industrial settings.

DIN rail mountable for convenient installation. Separate adjustment for starting torque and starting time. Power semiconductor bridged after motor startup to minimize losses. Reduces mechanical stress and starting noise in driven systems.

Equipped with LED display for operational status. Ideal for conveyors, fans, pumps, compressors, and packaging machinery. Complies with CE and EC/EN 60947-4-2 standards. Explore more automation and control gear products at EnvMart for your industrial and commercial electrical needs.
