The PGR-T Series resistors extend the resistance range of the PW series with another inorganically filled ceramic boat type resistor. The PGR-T is
entirely flameproof for use wherever MIL style power resitors are not mandatory and an industrial grade resistor is desired. The main flameproof characteristics are:
(1) Opens cleanly under overloads.
(2) The construction is completely inorganic and will not support combustion.
