Eaton NSB N101CS1C3A-MLS Non-Reversing Starters

Eaton NSB N101CS1C3A-MLS Non-Reversing Starters are three-pole motor starters designed for single-direction control of 3-phase motors. The unit uses a 24 VDC control coil and is rated for 27 A, making it suitable for motors up to 10 HP in a non-reversing configuration. The N101CS1C3A-MLS part number identifies this device within the NSB family and denotes the MLS control variant. With a 3-pole power contact arrangement, it provides a straightforward start/stop control path for a standard 3-phase motor, without reversing functionality. This configuration is appropriate for applications that require a dedicated start/stop control for motors up to 10 HP in 3-phase systems. From a design perspective, three-pole control ensures that all three hot lines are switched, providing reliable electrical isolation for the load. The non-reversing nature means direction changes would require a separate reversing arrangement.
