General Electric RTA2J Thermal Overload Relay

The General Electric RTA2J Thermal Overload Relay is a three‑pole protection device that provides motor overload protection when paired with GE CL‑series contactors (CL05–CL10). It is specified for applications requiring 64–75 A protection settings in three‑phase motor circuits, making it suitable for mid‑sized drives such as conveyors, pumps, fans, mixers, and other industrial equipment that rely on GE motor starters. As part of GE’s RT2J family of thermal overload relays, the RTA2J is designed to interrupt motor current during overload conditions, helping prevent insulation damage and motor burnout from sustained overcurrents. The relay integrates with GE control circuitry to deliver coordinated protection within a compact starter assembly, simplifying wiring and panel layout while maintaining reliable motor protection in demanding environments. When used with compatible GE contactors, the RTA2J forms a robust, easy‑to‑install solution for protecting three‑phase motors in HVAC, manufacturing, and process control applications.
