Elio Posted March 30, 2007 Report Share Posted March 30, 2007 Hi Nirav, Castel lock also known as castell key interlock is a mechanical interlock between two equipment. you can imagine it as two locks on two different equipment wiith only one key. If you are not allowed to parallel the two ups systems that you have you will need a castel key iinterlock for the MCCBs for example feeding your UPS board. Please note that it should be avoided to inetrlock two UPS supplies since you will be shutting down vital load for shifting from one ups supply to the other. Dual UPS systems are shoud be always ready for parallelling. Hope the above clarfied the matter if not please put more details in your question so i can answer your question.

jraef Posted April 1, 2007 Report Share Posted April 1, 2007 Also known as a "Kirk Key" interlock, because the largest supplier here in the US is called Kirk Key. http://www.kirkkey.com/ "He's not dead, he's just pinin' for the fjords!" Link to comment Share on other sites More sharing options...
Jeremy Posted June 23, 2007 Report Share Posted June 23, 2007 The "CASTELL KEY" is a key operated mechanical and electrical interlock system that can be used to prevent two or more systems from becoming active at any one time, or for protecting personel from gaining access to macinery whilst it is in use.
