  In contrast to the original type I seesaw mechanism that requires
right-handed Majorana neutrinos at energies much higher than the electroweak
scale, the so-called low scale seesaw models allow lighter masses for the
additional neutrinos. Here we propose an alternative low scale type I seesaw
model, where neither linear nor inverse seesaw mechanisms take place, but the
spontaneous breaking of a discrete symmetry at an energy scale much lower than
the model cutoff is responsible for the smallness of the light active neutrino
masses. In this scenario, the model is defined with minimal particle content,
where the right-handed Majorana neutrinos can have masses at the $\sim 50\mbox{
GeV}$ scale. The model is predictive in the neutrino sector having only four
effective parameters that allow to successfully reproduce the experimental
values of the six low energy neutrino observables.
