FAQs
The unit uses standard mounting with a common bezel and is designed for straightforward installation in typical switchgear enclosures. Its dimensions (7.49 in depth, 8.62 in height, 13.64 in width) and 12.7 lb weight should be accounted for in panel layout and mechanical clearances. Consider available clearance for RS485 cabling and wiring Termination as part of the installation plan.
Key specs include a 50/60 Hz frequency rating, 5 A contact rating (AC/DC), a burden of 10 W / 17 VA, and operating temperature from -20°C to 60°C. These parameters guide compatibility with control circuits and ensure reliable actuation within standard industrial power distribution environments.
Yes. Designed as a high-impedance bus differential relay, it targets robust bus section protection within 50/60 Hz systems. The standard mounting, RS485 communications (61850/MDBS/DNP3), and conformal coating support reliable operation in typical industrial environments, aiding fast fault isolation and uptime.
Compliance details are listed as provided by the manufacturer. Verify current certifications (for example CE, SIL, IP ratings) with Eaton to match regional and industry requirements for your application and market, using the datasheet and Eaton support resources as primary references.
The product carries Eaton’s policy of one year from installation or eighteen months from shipment, whichever occurs first. For prolonged asset planning, document warranty windows and plan preventive maintenance around this schedule, while leveraging Eaton support and the downloadable specification sheet for detailed lifecycle data.
