Allen-Bradley 193-A2H1 Thermal Overload Relay

Allen-Bradley 193-A2H1 Thermal Overload Relay is a 12–32 A overload protection device in the 193-series family, designed to protect three-phase AC motors by sensing current and using a thermal model to simulate motor heating and determine trip conditions. It is intended for use with compatible Allen-Bradley contactors in motor starter assemblies, offering adjustable full-load-amp (FLA) settings to match the protected motor’s rating. The 193-A2H1 provides reliable overload protection within the standard Allen-Bradley 193-series ecosystem, helping prevent motor damage from sustained overload, stall, or excessive running temperatures over long duty cycles.
