Product Description

The Eaton S811 soft start (MPN S811+U50N3S) is a 600V AC, three-phase unit with a 500 A output current, featuring a bypass and NEMA 1 enclosure, operating at 60/50 Hz with a 24V DC control voltage.

Frequently Asked Questions

What is the Eaton S811 soft start used for?

The Eaton S811 soft start is used to control the acceleration of three-phase AC motors, reducing mechanical stress and electrical inrush current. It is commonly applied in industrial settings such as pumps, conveyors, and compressors. This model includes a bypass contactor for energy efficiency and is housed in a NEMA 1 enclosure for indoor use.

What are the specifications of the Eaton S811+U50N3S?

The Eaton S811+U50N3S soft start has an output current rating of 500 A at 600V AC, with a control voltage of 24V DC. It operates at 60/50 Hz, is three-phase, includes a bypass contactor, and comes in a NEMA 1 enclosure. The manufacturer part number is S811+U50N3S.

Where to buy the Eaton S811+U50N3S worldwide?

How to select the correct Eaton soft start for a motor?

To select the correct Eaton soft start, match the motor's full-load current (FLC) and voltage to the soft start's output current and voltage ratings. Ensure the control voltage (e.g., 24V DC) matches your control system. Consider enclosure type (NEMA 1 for indoor) and whether bypass is needed for energy savings. Consult Eaton's selection guide for specific motor applications.
