Eaton Cutler-Hammer ECN0511AAA Starter

The Eaton Cutler-Hammer ECN0511AAA is a heavy-duty NEMA Size 1 motor starter engineered for reliable full-voltage non-reversing (FVNR) control in demanding industrial environments. This Freedom Series starter is rated for 27A continuous current and features a 120V AC coil, making it a standard choice for 3-phase motor applications requiring robust magnetic switching. Housed in a durable NEMA 1 enclosure, this non-combination unit is designed for indoor use where protection against dust and light indirect splashing is necessary. The 3-pole design incorporates silver cadmium oxide contacts to provide superior conductivity and arc erosion resistance. For comprehensive motor protection, this unit is typically paired with a thermal overload relay or C440 solid-state overload to prevent winding damage from overcurrent conditions. This magnetic motor starter is built to high technical standards, ensuring a long mechanical life for repetitive switching of HVACR blowers, pumps, and compressors.

• Enhanced Durability: The NEMA Size 1 frame is constructed with high-strength, temperature-resistant insulating materials for high-cycle industrial reliability.
• Efficient Footprint: The compact Freedom Series design minimizes enclosure space requirements while maintaining standard NEMA ratings.
• Versatile Control: Features a standard 110/120V coil compatible with most common control transformer outputs in commercial HVACR panels.
• Maintenance Friendly: Built with high-quality contacts that resist welding, extending the service life of the ECN0511AAA starter.

What is the maximum current rating for the ECN0511AAA?
This Eaton motor starter is rated for a maximum continuous current of 27 Amps, fitting the NEMA Size 1 classification for 3-phase motors.

Does this unit include an internal overload relay?
This specific configuration is a non-combination starter that typically requires the addition of a compatible heater pack or solid-state overload relay to provide motor branch circuit protection.

Is the ECN0511AAA suitable for outdoor installation?
No, this unit comes in a NEMA 1 enclosure, which is intended for indoor applications. For outdoor or washdown environments, a NEMA 3R, 4, or 4X rated enclosure would be required.
