The C440 Electronic Overload Relay delivers enhanced motor protection based on the ability to directly monitor motor current in each phase. Thermal modeling is performed electronically
with precision solid-state components. The electronics identify excessive current or phase loss and react to the condition with greater speed, reliability and repeatability than a traditional electromechanical device.
Modbus, Modbus TCP
Integral Ground Fault Protection; True simultaneous ground fault protection and communications capabilities; Two levels of communications capabilities: monitoring only, and monitoring and control; Monitors: Motor status (running, stopped, tripped, resetting); Individual RMS phase currents (A,B,C); Average of three-phase RMS
current; Percent thermal capacity & phase unbalance; Ground fault current and percent; Network ?Reset? capability
Flexible DIN and panel mounting; 4IN/2OUT I/O
