THERMOSTATS - PRECISION

3450CM/3455RM Series Ceramic and

Phenolic Manual Reset Thermostats

A temperature-sensitive bimetal disc, electrically isolated from the switch,

actuates the normally closed contacts. The contacts open when the

surface or ambient temperatures increase to the operating snap point of

the calibrated disc. The circuit will stay open above room ambient

temperature until the manual reset button is pressed. Response to

temperature changes is extremely rapid due to the inherently low mass

of the disc and the small size of the product.

Reset type:

Manual

Amperage capacity:

15 A resistive max.

Housing material:

Ceramic or phenolic

Operating temperature range:

52 °C to 232 °C [125 °F to 450 °F] (ceramic)

52 °C to 150 °C [125 °F to 302 °F] (phenolic)

Environmental exposure range:

10 °C to 260 °C [50 °F to 500 °F] (ceramic)

10 °C to 177 °C [50 °F to 350 °F] (phenolic)
