Overload Relay The overload relay provides motor protection by monitoring current and, in many models, temperature. When an overload is detected, it trips the control circuit to stop the motor and prevent damage. It is designed for use with standard industrial contactors and control panels. Key attributes - Function: protects motors from overload conditions and triggers a controlled trip to prevent damage. - Compatibility: works with common contactors and control circuits; suitable for integration in standard motor control panels. - Size and mounting: compact enclosure that fits within typical control cabinet spaces; suitable for new installations or retrofits. - Material and durability: robust housing designed for industrial environments; built to withstand typical panel conditions. - Performance: reliable and repeatable trip behavior within the specified range; many models offer adjustable trip current to match motor rating. Use scenarios - Conveyor drive: protects a motor during peak load or jam conditions to prevent damage. - Pump system: guards against overheating or stall when flow is reduced or blocked. - HVAC blower: protects the fan motor during startup and under high-load operation.
