EATON NEMA

Eaton NEMA enclosed non-reversing starters are available in NEMA Sizes 00, 0, 1, 2, 3, and 4. Current ratings range from 9 A for Size 00 up to 135 A for Size 4. Specific models include Size 00 at 9 A, Size 0 at 18 A, Size 1 at 27 A, Size 2 at 45 A, Size 3 at 90 A, and Size 4 at 135 A. These ratings correspond to standard three-phase motor horsepower at voltages such as 200 V, 230 V, 460 V, and 575 V. The starters are designed for full-voltage non-reversing applications and include electronic overload protection.

Eaton NEMA enclosed non-reversing starters are available with AC coils in 24 V, 120 V, 240 V, and 480 V. For example, SKU 6XEU2 has a 24 V AC coil, SKU 6VLF8 has a 240 V AC coil, and SKU 6XEY1 has a 480 V AC coil. The coil voltage determines the control circuit voltage and must match the available control power. These options allow integration with various control systems and plant standards.

Eaton NEMA enclosed non-reversing starters with electronic overloads use a solid-state overload relay that monitors motor current and trips on sustained overcurrent conditions. Unlike traditional thermal overloads, electronic overloads do not require heater elements, eliminating the need to select and stock specific heaters for each motor. This simplifies inventory and reduces setup time. The overload relay typically includes adjustments for trip class and current setting, allowing precise protection for the motor. It is designed to protect against overload, phase loss, and phase imbalance.

Eaton NEMA enclosed non-reversing starters come with one normally open (1NO) and one normally closed (1NC) auxiliary contact as standard. These contacts can be used for interlocking, signaling, or control logic. A pilot light is also included, providing local indication of the starter status. The pilot light voltage matches the coil voltage. Additional auxiliary contacts may be available as accessories, but the standard configuration includes 1NO/1NC. The enclosure typically has a cover-mounted pilot light and may include a selector switch or push buttons depending on the specific model.

Eaton NEMA enclosed non-reversing starters are typically supplied in NEMA Type 1 enclosures, which are intended for indoor use and provide protection against dust and light indirect splashing. Other enclosure types, such as NEMA 12 for dust-tight and drip-tight industrial environments, may be available. The enclosure type affects the environmental protection rating and must be selected based on the installation location. For washdown or outdoor applications, NEMA 4 or 4X enclosures would be required, but these are not indicated in the standard product listings.

Eaton NEMA enclosed non-reversing starters are designed for three-phase motor control. They have three poles, which are intended for three-phase power. While it is technically possible to use a three-pole starter for a single-phase motor by leaving one pole unused, this is not the intended application and may not provide proper overload protection. For single-phase motors, specific single-phase starters or manual motor protectors are recommended. The electronic overload in these starters is typically calibrated for three-phase current sensing, so using them on single-phase may result in improper protection.
