Bussmann by Eaton – Data Center Circuit Protection

I’m going to talk to you a little bit about the products that Eaton Bussmann Division has to offer for data centers.

First is power distribution in the white space. Their Compact Circuit Protector can go into multiple architectures. It can go into busway architecture where they’ll have bus drops using our DIN-rail mount version that will feed the electrical racks.

A lot of off-the-shelf components are only rated 10kA. This one’s rated 200kA. You don’t ever have to worry about where you apply it in the system or what you’re short circuit current is at that point in the system.

The other architecture is the RPP/PDU architecture where they have our Compact Circuit Protector that actually goes into their Quik-Spec panel board. That’s incorporated into the RPP or incorporated into the PDU and that in turn feeds the racks.

They also have an app that allows you to calculate the fault current in the system. They have our FC2 that’s available for Android and iPhone. With the app, you can quickly do a rough calculation on what your short circuit current is through your system, so that you’ll be able to tell if your devices are rated properly and whether you comply with the code or not.

The last piece in the data center is the actual rack. You have to come down off the bus or out of the RPP and the PDU down into the rack. Bussmann is launching a new product that goes into the rack power strips; the power supplies. It is the smallest UL 98 Fusible Disconnect in the industry. You can access the fuse without getting into the equipment, without removing any covers. Their SC20 or Class CC fuses go into these. They’re rated up to 30A. The fuses interlock with the handle so you need to turn it to the ‘Off’ position and then you can remove the fuse without any exposure to any live parts. They incorporate this into their devices that allows them to have that high short circuit current rating so that they can meet the National Electrical Code for these higher density systems.
