What accessories and renewal parts are available for the C440/XT Electronic Overload Relay?

All available accessories (communication modules, remote reset, safety cover, reset bar) are located in the catalog: Volume 5, Tab 5 - Motor Protection and Monitoring

Communication Modules

A number of communication accessories are available for the C440/XT Electronic Overload Relay. The basic communication option is accomplished by using the expansion module (C440-XCOM) which plugs into the underside of the overload relay, providing communications over Modbus RTU.  The advanced option allows for the use of industrial protocols including Ethernet/IP, Modbus TCP, DeviceNet, and PROFIBUS. In this case, the expansion module is combined with a communication module in order to provide motor information including run status, phase currents, thermal capacity, overload relay settings, and more. These options can be selected from the catalog link above.

Renewal Parts

There are no replacement parts available for the individual overload relays.
