1. Overload Relay What it is - A compact device that protects motors from thermal overload by monitoring current and tripping the control circuit when a preset limit is exceeded. - Designed to work with standard contactors and motor control circuits. Key benefits - Prolong motor life by preventing overheating and damage - Reduce unplanned downtime and costly repairs - Easy integration with common control panels and DIN rail or panel mounting - Adjustable trip settings to suit different motor sizes and operating conditions - Clear fault indication and straightforward reset for quick recovery Function and performance - Monitors motor current and temperature to detect overload conditions - Trips when the preset current exceeds the set limit, stopping the motor - Offers adjustable trip range to fit a variety of motors and operating profiles - Provides reliable protection with fast response in overload events Compatibility and construction - Compatible with standard motor control circuits and contactors - Available in multiple coil voltage options to match control systems - Compact, rugged enclosure suited for control panels - Enclosure material chosen for electrical control environments - Mounting options typically include DIN rail or panel mounting (model dependent) Physical attributes - Space efficient design for crowded control cabinets - Lightweight yet durable for industrial use Typical applications - Conveyor systems in manufacturing to guard motors against overload - Pumps and fans in HVAC or process industries subject to high starting or running currents - Automated machinery and machine tools where motor overload or stalls threaten equipment Notes - For exact trip current ranges, coil voltages, mounting options, and enclosure materials, consult the model-specific data sheet.
