摘要： An electrical switch with overcurrent protection communicates as a slave with a remote master station by sending return messages to the remote master station only in response to messages addressed to it. A portable unit plugs into the electrical switch and disables communications between the electrical switch and the remote master station. The portable unit then establishes communications with the electrical switch by sending a global message to the electrical switch requesting the unique address at successive baud rates until a return message containing the electrical switches' address is received. A communications module in the electrical switch transfers to a master mode in response to the global message in order to send the return message containing its unique address. It then reverts to the slave mode for response to subsequent messages from the portable unit containing the unique address. Either the remote master station or the portable unit can test the circuit breaker by sending a message containing a digital test current to the circuit breaker.

摘要： 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.

摘要： An over-voltage protection system including a phase bus connected to a phase conductor of an electrical system and one or more transient-suppressing lines connected to the phase bus. Each of the transient-suppressing lines includes a contactor and a transient-suppressing element. The contactor of each transient-suppressing line is selectively opened and closed by a processor, thereby protecting the transient suppressing element from excessive currents. Also a method of protecting at least one transient-suppressing element from over-voltage conditions including providing a transient-suppressing line including the at least one transient-suppressing element in parallel with a load, measuring at least one of a voltage signal representative of a voltage on the transient-suppressing line and a current signal representative of a current on the transient suppressing line, and selectively placing the transient-suppressing line in either an open condition or a closed condition based on at least one of the voltage signal and the current signal.

摘要： A circuit for controlling the orientation of magnetic fields is provided. The circuit has particular application to a flux shunt trip device in a circuit breaker. The flux shunt trip device has a spring-loaded plunger which when released to its extended position causes the circuit breaker to trip. Under normal operating conditions, the plunger is maintained in a retracted position by the force of a permanent magnet. A trip coil is mounted adjacent to the plunger. When the trip coil is energized a magnetic flux is generated opposing the magnetic flux of the permanent magnet. When the opposing flux neutralizes the flux of the permanent magnet the spring-loaded plunger is released to its trip position. A control circuit is provided to aid in maintaining the plunger in its retracted position under high current conditions close to, but below, the trip value. This control circuit acts to reverse the direction of current through the trip coil under these conditions such that a magnetic flux aiding that of the permanent magnet is generated. If a trip current is detected, the control circuit allows the current to flow in the normal direction through the trip coil, thus generating a magnetic flux opposing the permanent magnet which causes the plunger to be released and the breaker to trip.
