Relé de proteção de motor Eaton ZE-9 6-9 A, 3 polos, classe 10A, 1NO+1NC

The Eaton ZE-9 thermal overload relay stands out by offering precise protection for motors with rated currents between 6 and 9 A, directly mountable onto Eaton DILM7 to DILM15 contactors. Its selectable manual/automatic reset and phase failure sensitivity ensure dependable operation in demanding industrial environments.

Highlights

• Adjustable current setting from 6 to 9 A for flexible motor protection
• 3-pole thermal overload release with phase failure sensitivity per IEC/EN 60947-4-1
• 1 NO + 1 NC auxiliary contacts for control and signaling
• Direct mounting to Eaton DILM7, DILM9, DILM12, DILM15 contactors
• Selectable manual or automatic reset for operational flexibility

In daily use

Install the ZE-9 directly onto a compatible Eaton contactor to form a compact motor starter. Set the current dial to match your motor's full-load current, choose the reset mode, and wire the auxiliary contacts for status feedback. The relay trips on overload or phase loss, protecting your motor from damage. Its IP20 terminals and screw connections make wiring straightforward, while the wide operating temperature range (-25 to +55 °C) suits harsh environments.
