AutomationDirect RTD32400 Relay

The AutomationDirect RTD32-400 thermal overload relay provides adjustable motor protection for 3‑phase systems when used with GH15ET or GH15FT 45 mm frame contactors. It uses a bi‑metallic overload element and offers an adjustable trip current from 23.0 to 32.0 A, allowing precise matching to a motor’s full‑load amperage. A local reset enables manual restart after an overload, and the unit supports flexible mounting with direct‑mount power connections or DIN rail options to fit compact control panels. This relay is part of AutomationDirect’s RTD32 family and is designed to protect motors, conveyors, pumps, and fans by interrupting current when the sensed overload exceeds the set point, helping prevent motor damage in industrial applications. Designed for straightforward field adjustments, it allows technicians to fine-tune protection without removing the relay from the panel.
