💡 What is a thermal overload relay used for in motor control panels and motor starter assemblies? A thermal overload relay protects motors from sustained overcurrent by sensing heat and tripping before the motor is damaged. Here’s why installers put them in motor starters: - Prevents motor burnout by tripping at set current thresholds, ideal for IEC-based starters and control panels - Works with contactors like AF09-38 to create a complete motor starter for safe operation - Adjustable 10.0-13.0 A range lets you match motor full-load amps and comply with safety requirements
