August 3, 2010 - Eaton announces C440 and XT 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. With a patented, compact design, the 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.
DeviceNet, 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:
- Underwriters Laboratories (UL)
- Canadian Standards Association (CSA)
- Conformité Européenne (CE)
Additionally, the solid-state overload relays are Restriction of Hazardous Substances (RoHS) compliant.
