Overload relay What it does - An overload relay protects motors by monitoring current and tripping the circuit when a preset limit is exceeded, preventing overheating and damage. Benefits - Protects motor windings and wiring from overload, extending motor life - Reduces unplanned downtime and maintenance costs due to motor faults - Adjustable trip current lets you set protection to match the motor nameplate rating - Compact, rugged design for reliable operation in industrial environments - Easy integration with standard motor contactors and control circuits Key attributes - Function: provides overload protection for motor circuits - Compatibility: designed to work with common contactors and control panels - Size and mounting: compact form factor for easy installation in control cabinets - Material: robust housing suited for industrial use - Performance: reliable trip with adjustable settings and clear fault indication How to use - Install in the motor circuit alongside the contactor - Set the trip current to the motor nameplate current - Verify proper operation and ensure reset behavior matches system requirements Use scenarios - Conveyor belt drive in manufacturing lines to prevent motor burnout during start-up or jams - Industrial pump systems guarding against overheating when flow is blocked or restricted - HVAC fans or blowers in building automation protecting motors during high-load conditions
