Eaton Contactor Star Delta 240V 11 kW 22A 3 Poles IP20 SDAINL

Eaton 278336 SDAINLM22(230V50HZ,240V60HZ) Contactor Star Delta is engineered to manage three-phase induction motors by reducing starting current through a star-delta connection. Featuring a power rating of 11 kW and current rating of 22A at 240V, this starter ensures smooth motor startup with increased efficiency and reduced mechanical stress.

Designed with an IP20 ingress protection rating, this starter is safeguarded against solid foreign objects greater than 12 mm but does not provide liquid protection. It is built for open chassis installation within customized enclosures and supports direct mounting on standard 35mm DIN rail systems.

The starter includes a main, delta, and star contactor plus an adjustable timer ranging from 0 to 30 seconds, allowing fine control over motor starting sequences. Eaton SDAINLM22 model is compatible with Z00 or ZB type thermal overload relays for single phasing sensitivity conforming to IEC 947-4 standards. It is recommended that overload relays be purchased separately.

With a series designation SDAINL, the starter is certified for compliance with IE3 efficiency class motors, providing energy savings for industrial and commercial motor applications. Its compact size (68mm length, 158mm width, and 117mm depth) fits neatly on DIN rails facilitating easy integration in control panels.

Operating temperature ranges from -25°C to +40°C making it suitable for diverse industrial environments including manufacturing, electrical automation, HVAC motor controls, and water treatment plants. The star-delta starter reduces the starting current to roughly one-third compared to direct online starters, protecting electrical networks and extending motor life.

Suitable for IE3 efficiency class motors, promoting energy-efficient motor control. IP20 rating protects against solid objects larger than 12 mm. Three pole contactor providing robust switching capabilities. Compact dimensions enable seamless DIN rail mounting.

Adjustable timer from 0 to 30 seconds for flexible startup control. Operating temperature range from -25 to +40 degrees Celsius. Compliant with IEC 947 standards assuring quality and reliability. Open chassis design for installation in custom enclosures.

Requires separate purchase of overload relay for complete protection.

This Eaton star delta starter is ideal for industrial, manufacturing, electrical automation, HVAC, and water treatment applications. It is a trusted component for reducing motor starting current and improving operational safety.
