✔️ 3-phase motor overload protection, 20 to 25A, single-unit
The 3RU-style thermal overload relay protects 3-phase motors by monitoring current flow and ambient temperature, triggering a trip to stop power when preset limits are exceeded. It's commonly installed in motor control panels and switchgear to safeguard equipment and reduce downtime.
✅ Current range: 20 to 25 A
✅ 3-phase motor protection
✅ Current-dependent overload protection
✅ Industrial-grade protective relay module
✅ Suitable for motor starters and control panels
💡 What is a motor thermal overload relay used for in industrial electrical protection and how does it work?
It provides current-dependent protection for motors and is used in panels and starters to prevent overheating and damage.
- monitors current draw to detect overload - trips the motor circuit when the limit is reached - ideal for industrial control panels and motor drives - helps extend equipment life by reducing thermal stressDescription
