Eaton Expands Motor Protection Capabilities with New Solid-State Overload Relays, Improving System Reliability and Reducing Inventory


Eaton Corp. is expanding its motor protection solutions with the C440 and XT electronic overload relays, which provide motor protection. The electronic relays feature both integral ground fault protection and communications capabilities in a single, compact device. Developed for global use, the C440 and XT overload relays have a universal design and engineered for machinery original equipment manufacturers, project construction, and industrial end-user markets.


With a patented, compact design, the new electronic overload relays are easy to install, maintain and configure. Integral communications and ground fault protection means there are fewer devices to install. A light-emitting diode (LED) display on the device provides easy-to-see indication of device status and fault indication, allowing maintenance personnel to quickly determine if the device and motor are operating appropriately.


Customers can select the motor protection features they need, with selectable trip class, ground fault detection, phase imbalance and full load current (FLA) adjustment (5:1). Further, the C440 and XT overload relays can integrate into plant management systems, allowing network monitoring and providing asset protection.
