FVC sizing

[cherry2000]

Does anybody have a Table giving FVC starter sizes for various range of kW ratings ( heaters ) and also Lighting Transformers?
I am looking specifically at Siemens make ANSI design FVCs.

Sorry, but what does FVC stand for? Full Voltage Controller? Fixed Vacuum Contactor? Trying to guess but not getting there.

Full Voltage Contactor comprising of a MCCB or Short circui+o/l protection and a contactor for the switching function............

That information is in the Siemens catalog, but I admit it can be a bit daunting to navigate if you are unfamiliar with it (and I work for Siemens so I should know). What country are you in? I have direct links to the US information but that doesn't show the kW ratings as readily (it's in there, but buried).

The problem is, if yopu are looking at IEC style contactors, the listings will be for the individual components, i.e. the contactors and breakers separately,ort as a combination starters with Motor Switch Protectors, (not MCCBs and only up to 100A). Once you get over 100A, you have to look at the individual components separately.

For North America, you can look at "combination starters" which do use MCCBs, but they are fpor motors only because they use Mag-Only MCCBs and therefore must have an Overload Relay. So again, for a contactor only, you are left looking at the contactors and MCCBs separately.

Let me know where you are and what size you need and I'll see what I can find for you in Siemen's on-line info.
