Press Release Summary:
Featuring both integral ground fault protection and communications capabilities in single device, C440 and XT Relays directly monitor motor current in each phase and identify conditions that can lead to motor failure. Customers can select motor protection features they need, with selectable trip class, ground fault detection, phase imbalance, and full load current adjustment. DeviceNet(TM), PROFIBUS(TM), Modbus®, Modubus TCP, and Ethernet IP communication protocols are supported.

Eaton Expands Motor Protection Capabilities with New Solid-State Overload Relays, Improving System Reliability and Reducing Inventory
PITTSBURGH ... Diversified industrial manufacturer Eaton Corporation is expanding its motor protection solutions with the C440 and XT electronic overload relays, which provide customers with advanced, reliable and accurate 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 (OEMs), project construction and industrial end-user markets.
"The C440 and XT electronic overload relays are engineered to protect valuable assets, manage costs and maintain system integrity," said Raza Durrani, product manager, Eaton. "They directly monitor motor current in each phase and identify conditions that can lead to motor failure with greater speed, reliability and repeatability than traditional thermal devices. This can help customers reduce their total cost of ownership."
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.
Eaton C440 and XT overload relays feature integral communications capabilities, which allow the relays to easily integrate with customers' preferred industrial network. DeviceNetTM, PROFIBUSTM, Modbus®, Modubus TCP, Ethernet IP communication protocols are supported.
Designed for global applications, the overload relays allow for integration with National Electrical Manufacturer Association (NEMA), International Electrotechnical Commission (IEC), and Definite Purpose (DP) contactors. Further, they meet the following standards:
o Underwriters Laboratories (UL)
o Canadian Standards Association (CSA)
o Conformité Européenne (CE)
Additionally, the solid-state overload relays are Restriction of Hazardous Substances (RoHS) compliant.
