We do not have a breaker panel. We just have a server rack. The servers on the rack are connected to a power strip. The power strip is connected to a outlet. Is there a method to install the circuit breaker?

I agree the power point should be individected protected by a circuit breaker, if not you should change the setup or others can over load your circuit and cause a unscheduled interuption to you.
With your own protected circuir, If you still want individual switches or each server ETC. you can get swiched power boards (power rails) and you should not be using demestic ones as they are cheap and nasty and oftern made in china with a low quality control.
Remember quality = reliability and you sh

Sorry I didnt read your second comment. The other gentleman was correct as the circuit breaker is locaed in the supply switchboard that feeds the computer room circuits. As above this MUST be a seperate circuit for your security of service.

The breaker you have purchased is just a simple quick lag type breaker and could be used to replace the existing one if you particually want this one but Most likely is is just replacing a simlar purpose one.
If you do want to use it you can make a sub circuit in a plastic electrical enclosure box but I would not recommend this as it creats anouther point of failure. Also a Thing called the electrical descrimination must be considered. In other works each breaker down the line must trip before the one before it. If this is not addressed correctly the one in the switchboard may trip before the one you are installing thus it is a waist of time installing the new one.
Sorry to be long winded on this one but it is oftern a common question and issue so I hope this helps others. If you have any questions send me an email.
