Replacement of Electronic over current relay EOCRSS-60NW5 60A delay time : 15 sec coil : 380 V ?
The requested EOCR protection relay is very similar to TeSys LT4760* relay. It could be suggested as a closest match. It is not a 1:1 substitution though. There are some differences between the EOCRSS60NW5D and LT4760* relay such as the rated operational voltage, the auxiliary contacts composition, dimensions, standards and certifications that the product comply with.
For a quick comparison, please find attached the datasheet of one of the LT47 relays. You could compare this datasheet with the datasheet of the EOCRSS60NW5D relay.
