Eaton A8NES800T1 – Frequently Asked Questions
1) What amp settings can I get out of the Digitrip RMS 310 adjustable rating plug?
It covers a 400A to 800A range, with the trip unit configurable at 400A, 500A, 600A or 800A. That means one plug part number can set four different breaker trip ratings, which is why maintenance crews keep it on hand instead of stocking four fixed plugs.
2) Does buying this Digitrip rating plug include the trip unit or the breaker?
Rating plug only. The A8NES800T1 is sold as the adjustable rating plug by itself, so the Series G Frame ND breaker and its Digitrip RMS 310 trip unit must already be in place. Order the breaker or trip unit separately if you are building up an assembly from scratch.
3) I need to change a Series G breaker from 600A to 800A during commissioning. Is this the part I order?
That is exactly what it is for. On a Series G Frame ND breaker with a Digitrip RMS 310 trip unit, the rating plug sets the amperage, and this one covers 400A through 800A, so the same plug takes you from a 600A setting up to 800A without swapping the breaker.
4) Can an ABB SRPE30A20 rating plug be used in place of the Eaton A8NES800T1 Digitrip RMS 310 plug?
No. The Eaton A8NES800T1 is a Digitrip RMS 310 adjustable rating plug built specifically for Eaton Series G, Frame ND molded case breakers and adjusts across 400A to 800A. The ABB SRPE30A20 is an RMS1 series plug for the ABB Power Break II SE150 frame. Rating plugs key to the trip unit and breaker frame they were designed for, so each stays with its own breaker line.
5) Do I have to modify the breaker enclosure to install this rating plug?
No. The plug measures 2.3 in wide, 1.5 in deep and 1.5 in high, small enough to drop into the trip unit without cutting or altering the breaker enclosure, so panelboard and switchboard retrofits go in as-is.
6) Is the Eaton A8NES800T1 rating plug UL Listed for use in commercial distribution gear?
UL Listed, yes. That matters for an institutional or MRO buyer keeping a panelboard or switchboard assembly code compliant after a trip unit is reconfigured in the field.
7) Both the Eaton A8NES800T1 and the ABB SRPE30A20 are rating plugs - what actually differs between them?
They differ by breaker platform and trip system. The Eaton A8NES800T1 is a Digitrip RMS 310 plug for Series G, Frame ND breakers, covering 400A through 800A, UL Listed, in a 2.3 in wide by 1.5 in deep by 1.5 in high body. The ABB SRPE30A20 is an RMS1 series plug for the Power Break II SE150 frame. Neither is a generic amperage module, so the breaker in the panel decides which one you order.
