Eaton Contactor Overload Relay, 40 to 57A FLC Rating, 500V AC Control Voltage - ZB65 Series - 278459 ZB65-57

Protect your single-phase to 3-phase motors with this contactor overload relay from Eaton. It monitors the operating current of the motor and switches the contactor off in the event of an electrical overload or overcurrent. This process safeguards motors against overheating and protects them from damage caused by phase losses. Ambient temperature compensation ensures reliability and accuracy. Use this precision short-circuit-protection device for the motors in your commercial and industrial processes.

• Separate mount design is versatile for either DIN rail or direct panel mounting
• DIN rail mounting capability offers a space-saving installation solution for limited spaces
• Operating temperatures from -5°C to +55°C for use in demanding environments
• Screw terminal type ensures secure fastening in demanding environments where vibration is common

Why are contactors used in electrical systems?

Contactors are specially designed types of relay used to switch equipment or functions on and off. Contactors typically use lower power levels than the circuits they control. They're commonly used with industrial motors, as well as with lighting systems.
