Allen-Bradley 815DOV4 Manual Reset Overload Relay

Allen-Bradley 815-DOV4 Manual Reset Overload Relay is a size 3, single-pole overload protection device designed for use with Allen-Bradley motor starters to guard motors against overheating. It is rated for up to 600 V AC and supports a maximum full-load current of 90 A, making it suitable for mid‑range motor protection in control panels. The manual reset function requires a deliberate reset by the operator after an overload trip, preventing automatic restart until fault conditions are addressed. This device is part of the 815 family of overload relays and is intended for integration with compatible contactors in industrial electrical panels where reliable, resettable motor protection is needed.
