FAQs

Plan for semi-flush mounting and ensure removable terminals for field wiring. Verify input power compatibility with a 19-300 Vdc or 40-250 Vac supply and confirm Ethernet-based communications (61850, Mbus TCP, DNP3). Allocate space for 8 digital inputs and 9 digital outputs and provide proper shielding to minimize electrical noise. Also account for warranty registration and the potential need for conformal coating in harsher environments.
Key specs include 8 digital inputs, 9 digital outputs, 2 current sensing inputs, and a 50/60 Hz operating frequency. It supports power inputs of 19-300 Vdc and 40-250 Vac, and communications via 61850, Mbus TCP, or DNP3 TCP/UDP over Ethernet RJ45. The device offers transformer protection features such as differential protection and zone selective interlocking with a robust form factor.
Ideal for substations, utility-scale transformers, OEM equipment, and industrial power systems requiring reliable transformer protection with flexible Ethernet communications. It fits retrofit projects and new builds where protocol interoperability and compact protection logic are priorities, enabling faster commissioning and easier integration with existing protection schemes.
The data specifies Compliances as Contact Manufacturer, so verify Eaton’s current certification status (such as CE) with the vendor. The device supports modern protection protocols (61850, Mbus TCP, DNP3), which are commonly required in regulated environments. Always confirm with Eaton for the latest compliance documentation before installation.
Warranty is Eaton Selling Policy 25-000, providing one year from installation or eighteen months from shipment, whichever occurs first. extended support and service options are available through Eaton’s channels. This reduces downtime risk, streamlines maintenance, and supports a lower total cost of ownership for transformer protection deployments.
