The Eaton Moeller series ZB thermal overload relay ZB12-10 provides reliable motor protection for starters and control panels. Its adjustable 6 to 10 A setting and Class 10 tripping characteristic help prevent thermal overload and phase loss damage, keeping drives and critical equipment running efficiently. Built for quick coordination in motor control centers, it pairs seamlessly with contactors to deliver compact, dependable protection.

Engineered for demanding industrial environments, ZB12-10 supports rated operational voltages up to 690 V and offers 6 kV impulse withstand (overvoltage category III, pollution degree 3). Phase-failure sensitivity in accordance with IEC/EN 60947-4-1, trip-free release, and manual/auto reset enable safe, predictable behavior. Direct mounting with finger-safe IP20 terminals and robust screw connections simplifies wiring, while a wide ambient range from -25 to +55 °C and SCCR up to 100 kA with proper fusing (UL/CSA) support robust system design and compliance.

Ideal for OEMs and panel builders integrating motor starters for pumps, fans, and conveyors, this relay combines precise adjustment with clear auxiliary signaling to streamline commissioning and service, and it is backed by a 1-year warranty to support reliable operation throughout its service life.
