THERMOSTATS

D1 and D3 MODELS

Double-Pole or Three-Pole, Single-Throw, Snap Action,
Direct Acting, Bulb and Capillary Type Thermostats.

These temperature controls, with normally closed contacts, open on temperature rise, and are suitable for controlling the temperature of a wide variety of electrically heated liquids, solids, surfaces, air and other gases. These thermostats may be used in ovens, cleaning baths, platens, pipelines and sterilizing equipment, to name only a few. The expansion and contraction of the fluid in the sensing bulb controls the temperature of these thermostats.
