Eaton Improves System Reliability by Expanding Motor Protection Capabilities with Broader Range of Electronic Overload Relays
“Eaton is helping customers advance lean processes through a range of innovative industrial control solutions that simplify control and reduce equipment and space requirements,” said Raza Durrani, product manager at Eaton. “The expanded electronic overload relay solutions improve system reliability for industrial customers.”
Eaton’s electronic overload relays are now available up to 175 ampere (A) and feature integral ground fault protection and communications capabilities in a single, compact device. With a universal design, the electronic overload relays provide an integrated starter solution for applications requiring National Electrical Manufacturer Association (NEMA) size 4 and 185A International Electrotechnical Commission (IEC) contactors. Additionally, the new frame is available in cable-in/cable-out and pass-through versions, making it well suited for upgrading existing customer infrastructure.
With a patented, compact design, Eaton electronic overload relays are easy to install, maintain and configure. 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®, Modbus TCP, Ethernet/IP communication protocols are supported.
Designed for global applications, the electronic overload relays meet Underwriters Laboratories (UL), Canadian Standards Association (CSA) and Conformité Européenne (CE) standards. Additionally, the solid-state overload relays are Restriction of Hazardous Substances (RoHS) compliant.
