💡 What is a differential thermal overload relay and how does phase unbalance protection help motors?

In plain terms, it guards motor windings against overheating by sensing differential current and balancing faults, then shuts the circuit to prevent damage.

• Differential sensing detects heat buildup caused by uneven load
• Phase unbalance protection prevents winding overheating and insulation stress
• Designed to work with TeSys K contactors for compact motor control
• Standards compliance: IEC, UL, CSA, EAC and RoHs/Reach standards
