90°F Close On-Rise (normally open) 3/4” Disc Thermostat
The circuit will CLOSE when the temperature reaches 90°F (± 9°F), typically turning something on, and the circuit will OPEN when the temperature falls to 70°F (± 9°F), typically turning something off.
These direct sensing thermostats are larger than standard thermostats, giving them an even more powerful bimetallic disc and a higher electrical rating (25A). They are ideal for use with heating and air conditioning systems as well as with industrial equipment.
Designed for maximum airflow around the thermostat to give quick and accurate response.
Featuring a bimetallic, temperature-sensitive disc for snap-action in opening and closing the switch contacts. The bimetallic disc is thermally and electrically insulated from the electrical circuit, eliminating self-heating effects. Only the temperature of the controlled equipment causes the switch to actuate.
Switch operation is rapid and positive due to the characteristics of the bimetallic disc and the wiping action of the current-carrying contacts. Contact chattering is virtually eliminated, as is false cycling and sparking.
