Electric motor protection relay C440 series

earth-leakagevoltagecurrent

Increased flexibility, enhanced protection The C440/XTOE electronic overload relay delivers enhanced motor protection and communications capabilities in a single compact device, directly monitoring motor current in each phase. Thermal modeling is performed electronically with precision solid-state components. Core features of C440 electronic motor protection relays • Electronics accurately identify excessive current or phase loss and react to conditions with greater speed, reliability and repeatability than traditional electromechanical devices • Integral ground fault protection supporting true simultaneous ground fault protection and communications – translates to reduced inventory, quicker installation time and a reduced physical footprint • Flexible communication with optional I/O enables easy integration into plant management systems for remote monitoring and control • Remote monitoring capabilities to discover changes in your system protects against unnecessary downtime • LED indicator provides predictive indication that allows users to determine the status of the overload as well as an impending trip to provide enhanced protection of your most important assets • Wide FLA adjustment (5:1) and selectable trip class improves return on investment by reducing inventory carrying costs • Patented thermal modeling design results in increased motor life • Voltage loss restart provides automatic revival after outages
