278459 ZB65-57 Eaton Overload Relay - 1NO + 1NC, 40 → 57 A F.L.C, 57 A Contact Rating, 7.5 W, 500 Vac

ZB65 Overload Relays_x000D_ These are for use with DILM contactors DILM40 to DILM65_x000D_ Fits below DILM 40 to DILM65 contactors_x000D_ Provides short circuit protection for motors_x000D_ When fitting overload relay remote from contactor, or using more than one overload relay, use remote mounting base (stock no. 513-0336)_x000D_ Eaton Contactor Overload Relay, 40 to 57A FLC Rating, 500V AC Control Voltage - ZB65 Series - 278459 ZB65-57_x000D_ 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._x000D_ • Separate mount design is versatile for either DIN rail or direct panel mounting_x000D_ • DIN rail mounting capability offers a space-saving installation solution for limited spaces_x000D_ • Operating temperatures from -5°C to +55°C for use in demanding environments_x000D_ • Screw terminal type ensures secure fastening in demanding environments where vibration is common_x000D_ Why are contactors used in electrical systems?_x000D_ 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._x000D_ Note_x000D_ Eaton formerly known as Moeller
