Square D 9065GO-1R Thermal Overload Relay Open Type

Square D 9065GO-1R is a melting‑alloy, open‑type thermal overload relay designed to protect motors in open‑type starter circuits. Part of Schneider Electric’s Square D 9065 family, this relay uses a melting alloy thermal element to interrupt motor current when overheating occurs, providing dependable protection without electronics inside the relay body. The GO‑1R configuration is intended for open‑type installation and is paired with compatible Square D contactors to form a complete motor protection solution in control panels or remote enclosures. Used with open‑type motor starters, it guards against overload conditions that can shorten motor life or cause torque and startup issues, helping to prevent nuisance trips and equipment damage in industrial applications. Notably, 9065 melting‑alloy overload relays are offered in multiple sizes and configurations to match a range of motor current ratings and mounting arrangements; consult the 9065 overload catalog for compatibility notes and installation guidelines when selecting a replacement or retrofit. The GO‑series emphasizes straightforward replacement in existing panels, with a proven, maintenance‑friendly design that relies on a time‑tested thermal trip mechanism rather than solid‑state sensing.
