Overload Relay - Function: Monitors motor current and provides protection against excessive load. If current or temperature exceeds set limits, it trips the connected contactor to stop the motor. Reset options may be manual or automatic depending on model. - Why you need it: Prevents motor overheating and winding damage, reduces unplanned downtime, protects wiring, and extends motor life. - Key attributes: Adjustable current setting to fit motor rating; fast, reliable trip; compatible with standard motor starters and contactors; compact panel-mount design; rugged insulating housing with standard terminals. - Compatibility: Designed for use with common 3-phase motor circuits and control panels; works with most standard contactors in new or retrofit installations. - Physical design: compact footprint suitable for tight panels; simple wiring with screw terminals. - Performance: Thermal overload protection with predictable trip behavior; suitable for a broad range of motor currents; quick reset to minimize downtime. - Use scenarios: - Protect a conveyor line drive motor from jams or overloads. - Guard a centrifugal pump motor against blockage or dry running. - Protect an HVAC or cooling fan motor under variable load conditions. - Note: Refer to the product datasheet for exact current rating ranges, wiring details, and reset method.
