RS PRO Star Delta Starter Motor, 230V AC, 22 kW, 3 Phase, IP65, Surface Mount 725-5557

The RS PRO 725-5557 Star Delta Starter Motor is a reliable device designed to safely start and protect 3-phase induction motors by reducing the starting current. Operating at 230V AC with a power rating of 22 kW, this starter uses a star connection to initially limit inrush current, then switches to a delta configuration when the motor reaches about 80% of its rated speed.

This starter is ideal for industrial equipment such as conveyors, pumps, and various engineering machinery requiring frequent motor starts and stops. Its robust moulded plastic enclosure offers excellent durability and impact resistance, coupled with an IP65 rating for protection against dust and water spray.

Mounting is surface-type with compact dimensions of 220 mm length, 280 mm width, and 170 mm depth, facilitating easy installation in control panels. It supports current ratings from 24 A up to 32 A across three poles, complying with IEC/EN 60947-1 and IEC/EN 60947-4-1 standards ensuring high safety and performance.

The RS PRO 725-5557 is manufactured in Italy, reflecting superior engineering standards. Its capability to operate up to 30 starts per hour makes it highly suitable for applications demanding frequent cycling of motors.
