As a world leader in appliance motor protection, Sensata Technologies has developed the 3MP for 120 and
230VAC applications to operate in wider temperatures and current ranges than offered by existing
protection solutions. In providing consistent performance characteristics and excellent reliability,
its features anticipate future technical protection requirements on the AC motor market.
The 3MP permits moving the motor protector location outside the winding, providing the motor manufacturer
with extra flexibility during the manufacturing process.
Recent certification as a thermal cut-out device combined with its unique current sensitivity positions the
3MP as an advanced and effective solution to protect toroidal transformers.
