Protective Relays
Catalog Number Selection
The catalog number
identification chart defines
the electrical characteristics
and operation features
included in the ETR-4000.
For example, if the catalog
number were ETR-3000A0BA1,
the device would have the
following:
ETR-4000
(A)–8 Digital Inputs,
9 Output Relays
(0)–5A/1A phase and ground
CTs, Power Supply Range:
19-300 Vdc, 40–250 Vac
(B)–Modbus-RTU (RS-485)
(A)–Without Conformal
Coating
(1)–Projection Panel Mount
ETR-4000 Eaton Transformer Protection Relay
