Automation Direct RTD32 1400 Thermal Overload Relay

The RTD32-1400 Thermal Overload Relay from AutomationDirect is a bi-metallic overload protection device designed to work with GH15CN–GH15FT contactors. It offers an adjustable current range of 10.0–14.0 A, enabling precise motor protection within that setting, and includes phase-loss sensitivity to trip when a single phase is lost. The relay mounts directly to the contactor and provides direct-mount power connections, with DIN rail mounting available as an alternative for flexible panel layouts. As part of AutomationDirect’s RTD32 family, the RTD32-1400 also provides a 1 normally open and 1 normally closed auxiliary contact for signaling or interlocking. Typical applications include protecting small to mid-size motors in conveyors, pumps, fans, and other equipment powered by GH15 contactors, where reliable thermal protection and quick interlock signaling are important. The combination of a robust bi-metallic element, adjustable trip point, and integrated auxiliary contact makes the RTD32-1400 a compact, field-proven option for industrial motor protection in standard control voltages.
