Allen-Bradley 815-DOV4 NSNBC01 is a manual-reset overload relay in the 815 family that protects motors by monitoring current and tripping the associated starter when overload is detected. Classified as Bulletin 815, Series K, it provides current-based motor protection for motors up to 90 A full-load current and is rated for a maximum of 600 V AC. This model pairs with compatible Allen-Bradley contactors to interrupt power during overload conditions and features a single-relay configuration for straightforward protection logic. Common applications include industrial motor protection in conveyors, pumps, and machinery where reliable overload protection and a manual reset are required.
