Description

Littelfuse three electrode PMT3(310) series GDTs are

designed primarily to protect telecommunications

equipment requiring simultaneous crowbar action

of two signal lines. GDTs function as switches;

dissipating a minimum amount of energy and can

handle much higher currents than other types of

transient voltage protection.
