Eaton 3PMB400R – Frequently Asked Questions

1) Will the Eaton Type KD meter service module work on a 120/208V three-phase service?
Yes. The Eaton Type KD MCB meter service module is built for 3-phase, 120/208V service, which is the common wye voltage on commercial and multi-family buildings. It is not a 120/240V single-phase device, so if the incoming service is single-phase you need different service equipment.
2) What is the difference between the 1PMB400R and the 3PMB400R Eaton meter modules?
Both are Type KD MCB meter service modules for 120/208V 3-phase service; the difference is the pole configuration. 1PMB400R is the single-position/1-pole ordering code and 3PMB400R is the 3-pole code. Pick the one that matches the breaker poles your service layout calls for, since they are separate order numbers and not field-interchangeable.
3) Does this Eaton module include the main breaker, or do I add one?
The main breaker is part of it. This is a Type KD MCB unit, meaning the meter position and the main circuit breaker protection are combined in one module rather than metering only. If you want a meter socket with no main disconnect, that is a different piece of equipment.
4) Do I need to buy separate lugs or connectors to terminate service conductors in this Eaton meter module?
No extra termination hardware is needed. The module ships with lugs so service conductors land directly in the unit, which is one less line item on a service-entrance material list.
5) Can I use this Eaton Power Defense meter module on a service upgrade instead of new construction?
Both work. The Type KD MCB meter service module is used on new-construction metered service entrances and on service upgrade and retrofit projects, as well as in panelboard and switchgear metering assemblies. What governs the retrofit is whether the existing service is 3-phase 120/208V and whether the pole configuration matches.
6) Is a Type KD MCB meter module the right choice for a multi-family building's metered service?
It suits that job. Combining the meter position with main breaker protection in a single module is aimed at metered service entrances and 3-phase commercial or multi-family distribution, so a property manager or electrical contractor standardizing meter equipment across a 208V building is the intended user. For a single-phase residential service, look to single-phase meter equipment instead.
7) What exact part numbers do I quote for the Eaton Type KD meter service module?
Two Eaton MPNs cover it: 1PMB400R and 3PMB400R. Both are Power Defense series Type KD MCB meter service modules for 120/208V 3-phase service with lugs. Quote by MPN plus the pole configuration so the pole count is not lost in translation.
