Amp-Trap® is a trademark of the Ferraz-Shawmut company that covers a line of fast, current-limiting fuses. These fuses are typically used to limit the fault current available at a given point in the electrical system.
A common entertainment industry application of Amp-Trap fuses is to place them between a large bus and individual rack busses in a multi-rack dimmer bank.
