A crowbar module includes first and second electrical terminals, a module housing, and first and second crowbar units. The first crowbar unit is disposed in the module housing and includes a first thyristor electrically connected between the first and second electrical terminals. The second crowbar unit is disposed in the module housing and includes a second thyristor electrically connected between the first and second electrical terminals in electrical parallel with the first crowbar unit.

Devices for overvoltage, overcurrent and arc flash protection

A surge protective device (SPD) includes a first electrical terminal, a second electrical terminal, and an overvoltage protection circuit connected between the first and second electrical terminals. The overvoltage protection circuit includes a gas discharge tube and a current management circuit connected in series to the gas discharge tube. The current management circuit includes a varistor and a resistor that are connected in parallel between a first node of the current management circuit and a second node of the current management circuit.
