Eaton CHPMIKCSR – Frequently Asked Questions

1) What does the Eaton CHPMIKCSR mechanical interlock actually do in a panel?
The Eaton CH mechanical interlock, model CHPMIKCSR, is a mechanical kit that prevents two connected devices from being closed at the same time. That's the classic utility-versus-generator arrangement: one breaker can be on, never both. It is a three-phase, 225 A rated assembly with a 10 kAIC interrupt rating in a NEMA 1 enclosure. It is not a transfer switch and it does not switch anything automatically, an operator moves the handle.
2) Can I mount the Eaton CHPMIKCSR interlock outdoors or in a wet location?
No. The enclosure rating is NEMA 1, which is a general purpose indoor rating. It guards against dust and incidental contact with live parts, nothing more. For an exterior wall, a parking structure, a wash-down area, or anywhere rain or hose spray reaches, you need a rainproof or watertight enclosure instead. Keep this one in a clean, dry electrical room or interior utility space.
3) Will a 10 kAIC interrupt rating be enough for my service?
Only if the available fault current at the point of installation is at or below 10 kAIC, which is the rating carried here. On a small commercial service well downstream of the transformer that is usually fine. Close to a large pad-mount transformer, or on a big multi-family or industrial service, available fault current often runs well above 10 kA and this assembly would be under-rated. Have the fault current calculated at the panel location before you commit.
4) Is the Eaton CHPMIKCSR suitable for single-phase residential service?
No. This one is built for three-phase systems and rated 225 A. For a single-phase house panel you want the single-phase version of the CH interlock, not this assembly. The three-phase configuration is what makes it appropriate for commercial, light industrial, and multi-unit three-phase distribution.
5) Can I use the Eaton CHPMIKCSR as a generator transfer setup for a commercial building?
It works as manual transfer control. The mechanical interlock physically blocks both sources being closed together, so utility and generator can never be paralleled. It is manual, though, so someone has to be on site to throw the handles during an outage. If the building needs unattended changeover, such as life safety or refrigerated load, specify an automatic transfer switch instead. Also confirm your generator and main breaker sizing fits the 225 A three-phase rating.
6) Which Eaton loadcenter line does this interlock belong to?
It is part of Eaton's CH line, ordered as model CHPMIKCSR. CH and BR are separate breaker and loadcenter families at Eaton and their accessories are not cross-compatible, so if your panel is BR this interlock is the wrong part. Match the panel family before ordering.
7) What are the dimensions and weight of the Eaton CH 225A interlock enclosure?
The stated dimensions are 34.1 in length/depth, 14.3 in width, and 1.1 in height, at 8.6 lb. It's a light, flat assembly, so one person can hold it while fastening, but plan wall or panel space for the 34.1 in dimension before you lay out the electrical room.
8) Is the bus aluminum or copper on the Eaton CH 225A interlock?
Aluminum bus. That matters on termination: aluminum needs correctly rated connectors and lugs, proper torque to the marked value, and a re-torque check after the first heat cycles. If your specification calls for copper bus throughout, this assembly will not meet it.
