9991SEA11

The 9991SEA11 contactor, part of Schneider Electric's Square D series, exhibits robust specifications ideal for industrial applications. This contactor is classified as a NEMA Size 3 unit, indicating its suitability for moderate to heavy-duty operations. Measuring approximately 800.10 mm in height, 461.01 mm in width, and 243.33 mm in depth, its substantial dimensions reflect the device's capabilities. The contactor features three closing plates, which enhance its reliability during operation.

The input voltage range for this unit extends from 120 to 240 V, allowing it to power motors rated up to 10 hp. Designed for a standard operating frequency of 60 Hz, it effectively supports various industrial applications. The NEMA 12 enclosure type ensures that the contactor is adequately protected from dust and other contaminants, making it suitable for use in harsher environments.

Furthermore, the operational humidity limit is set at 80% relative humidity, ensuring consistent performance without concerns about condensation. The 9991SEA11 is also rated for storage in similar humidity conditions, thus maintaining reliability even when not in active use. This contactor can operate effectively at altitudes reaching 1000 meters above sea level, extending its usability in various geographical locations.
