Eaton SDAINL Star Delta Starter, 7.5 kW, 230V AC, 3 Phase, IP20 278311 SDAINLM16(230V50HZ,240V60HZ)

Eaton 278311 SDAINLM16(230V50HZ,240V60HZ) Star Delta Starter is a robust solution designed to ensure reliable starting and operation of three-phase induction motors rated at 7.5 kW using a 230V AC, 3-phase supply with IP20 protection. This starter operates by initially connecting the motor windings in a star configuration, which limits the initial inrush current, thereby protecting electrical components and circuits.

Once the motor reaches an adequate speed, the starter switches the winding connections to a delta configuration to provide full power, minimizing mechanical stress and increasing the motor's longevity. This design feature makes the starter suitable for demanding industrial environments such as manufacturing plants and power distribution setups.

The starter includes a 16A current rating and supports up to 30 starts per hour, with a rapid switching time of 20 seconds to ensure smooth operational transitions. Compact dimensions of 82 mm height, 158 mm width, and 117 mm depth allow space-efficient installations. The screw connection type provides a secure and stable hold on wires, reducing maintenance needs.

Energy efficiency is enhanced by a low heat dissipation of only 0.94W per pole, contributing to lower energy consumption and extended component life. The operating temperature range between -25°C and +60°C enables the device to perform reliably in a variety of industrial and commercial settings.

Conforming to CE standards and manufactured in Romania, this Eaton SDAINL starter represents a high-quality choice for industrial motor control applications. It is ideal for sectors such as manufacturing, power utilities, and industrial automation systems.
