Automation Direct RTD32-400 Thermal Overload Relay

Automation Direct's RTD32-400 Thermal Overload Relay is a dedicated motor-overload protection device in the RTD32 family. It is designed to work with GH15BN to GH15FT series contactors, letting you build compact motor-starter packages for 3-phase and single-phase motors in automation panels. The RTD32-400 provides adjustable overload protection with a full-load current (FLA) range of 2.7 to 4.0 A, allowing you to tailor protection to the motor size and operating conditions and reduce nuisance trips. As a part of the RTD32 lineup, this model coordinates with the selected contactor to interrupt the circuit if current exceeds the preset threshold, helping prevent motor winding damage during overload events. The PN RTD32-400 is one variant among multiple RTD32 options designed to cover a spectrum of motor currents, enabling engineers to select the appropriate level of thermal protection for their application while keeping wiring and control interfaces consistent with Automation Direct's GH-series protectors.
