Eaton Overload Relay 1 NO/1 NC, 40A, 57 A F.L.C, 57A Contact Rating, 7.5 W Power, 500V AC Control Voltage ZB65

Eaton ZB65 Overload Relay, model ZB65, is engineered for industrial and commercial motor protection applications requiring reliable current monitoring and overload safety. Rated for motor full load current between 40 and 57 amperes, and a relay contact current of 57A, this device safely interrupts motor power at signs of overload or phase failure, preventing motor damage due to overheating.

Designed with a 7.5 watt power rating and a control voltage of 500V AC, the relay supports direct mounting in panels or with optional DIN rail installation, offering flexible mounting solutions in constrained environments. Its screw terminal type guarantees robust electrical connections enduring heavy vibrations commonly found in industrial settings.

The ZB65 series features an adjustable current range from 40 to 57 amperes, enabling fine tuning to specific motor requirements. Resetting mechanisms include both automatic and manual methods to accommodate different process control needs with ease of operation under varying conditions.

With a compact footprint measuring 172 mm in length, 60 mm in width, and 132 mm in depth, this overload relay fits efficiently in control cabinets. It maintains excellent operational integrity within ambient temperatures between -5 and +55 degrees Celsius, making it suitable for demanding environments.

Compliance with a broad array of international standards such as IEC/EN 60947-4-1, UL 508, CSA, and CE approvals underscores the ZB65's quality and safety credentials. Its IP00 rating means it must be installed in protected environments to avoid exposure to particulates and liquids.

Adjustable current range allows precise motor protection to reduce downtime. One normally open and one normally closed auxiliary contact provide control and signaling options. Direct and DIN rail mounting options enable versatile installation in industrial panels.

Robust construction suitable for commercial and industrial use cases. Ideal for safeguarding motors from short circuits, overloads, and phase failures.

This Eaton overload relay is a suitable choice for engineers and maintenance professionals seeking reliable protection for single-phase to three-phase motors in manufacturing lines, HVAC systems, and industrial automation setups.
