B-LINE 8MES500T – Frequently Asked Questions
1) Will an Eaton Series C rating plug work in any brand of molded case breaker?
No. The 8MES500T is built for Eaton Series C molded case circuit breakers with electronic trip units. Rating plugs are keyed to the manufacturer's trip unit and frame, so it will not fit a Square D, Siemens, or ABB breaker. Match the plug to the Eaton frame you actually have in the panel.
2) Is the 8MES500T a circuit breaker or just an accessory?
It is an accessory only. The 8MES500T is a rating plug for an Eaton molded case circuit breaker, not a breaker itself. You install it into an existing electronic trip breaker to establish the amp rating. If you need the breaker, order the breaker separately.
3) Can I change the amp rating of an Eaton Series C breaker without replacing the whole breaker?
That is exactly what a rating plug is for. Swapping to a 500A plug like the 8MES500T re-rates the electronic trip unit to 500 amps, so a facility that has re-sized a feeder can adjust the breaker in place instead of pulling and replacing the device. The frame itself must be rated to carry that current.
4) What part number should I give my distributor for the 500 amp Eaton Series C rating plug?
Order it as Eaton 8MES500T. That manufacturer part number covers the 500A Series C rating plug; there are no finish, size, or handing choices to specify with it.
