The C440 and XT electronic overload relays provide motor protection. They feature both integral ground fault protection and communications capabilities, in a single, compact device. 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, which can help customers reduce their total cost of ownership, claims the company. 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 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. According to the manufacturer, 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). The C440 and XT relays feature integral communications capabilities, which allow the relays to easily integrate with customers’ preferred industrial network. DeviceNet™, Profibus®, Modbus®, Modbus TCP, and Ethernet IP communication protocols are supported.
