Abstract
Trip profiles for electrical switches such as circuit breakers and overload relays can be generated, and when appropriate, coordinated, in a remote processor such as a personal computer. The profiles, with the addresses of the associated electrical switches are transferred into non-volatile memory in a portable unit. This portable unit is transported to the site of the electrical switches where it is interfaced with the appropriate electrical switch for loading of the assigned profile into the switch. In addition, the profiles stored in the electrical switches can be loaded into the portable unit for transport back to the remote unit for verification and/or modification.
