Lug assemblies include a housing with at least one internal printed circuit board with electronics and lugs. The lugs attach to cables providing power/current. The printed circuit board includes at least one electrical ground connector and at least one electrical contact connector. The lug assemblies include terminals that indirectly electrically couple the cables to terminals of switching devices such as circuit breakers.

Lug assemblies and related electrical apparatus and methods

An electrical surge protection device is structured to be installed on an electrical enclosure and to be electrically connected between one or more line conductors and one or more ground or neutral conductors. The electrical surge protection device includes a support that is structured to be installed on the electrical enclosure and a number of varistors or other electrical components that will, in the event of a voltage surge on a line conductor, shunt electrical energy from the voltage surge to the ground or neutral conductor with which it is connected. The electrical surge protection device advantageously further includes a shield apparatus that is structured to restrain an increased ambient pressure and that is electrically conductive and is electrically connected with the ground or neutral conductor.

Electrical surge protection device

An electrical switching apparatus includes a first terminal, a second terminal, a neutral conductor, separable contacts electrically connected between the terminals, an operating mechanism to open and close the contacts, a fused varistor electrically connected between the first terminal and the neutral conductor; and a trip mechanism including a trip coil cooperating with the operating mechanism to trip open the contacts. A second varistor is electrically connected in series with the trip coil between the first terminal and the neutral conductor. A thyristor is electrically connected in parallel with the second varistor. An overvoltage detection circuit is electrically interconnected with and causes the thyristor to energize the trip coil and cause the trip mechanism to trip open the contacts responsive to overvoltage between the first terminal and the neutral conductor.
