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.
