EATON Thermal Overload Relay ZE-1.0, 0.63-1.0 A, 690 V AC, 1NO+1NC, Class 10A, IP20 014376

Thermal overload relay engineered to protect small motors up to 1.0 A with precise thermal tripping and phase failure sensitivity. The ZE-1.0 pairs directly with Eaton DILM7–DILM15 contactors, offering a compact IP20 solution for motor starters in industrial control panels.

Advantages

This relay delivers reliable overload protection with a Class 10A tripping characteristic, ensuring motors disconnect quickly under locked-rotor or sustained overload conditions. Its phase failure sensitivity guards against single-phasing, a common cause of motor burnout. The auxiliary contact set (1NO+1NC) provides flexible signaling for control circuits, while manual/automatic reset modes adapt to different operational needs. Direct mounting to compatible contactors reduces wiring and saves panel space.

Suitable for

• Three-phase motors with rated currents between 0.63 A and 1.0 A
• Industrial control panels requiring compact motor starters
• Applications using Eaton DILM7, DILM9, DILM12, or DILM15 contactors
• Machinery where phase failure protection is mandatory
