THERMOSTATS - COMMERCIAL
2450RC/2450RCH/2455RC Series
Ceramic Automatic 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. 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: Automatic
Amperage capacity: 15 A resistive max.
Housing material: Ceramic
Operating temperature range: 0 °C to 260 °C [32 °F to 500 °F]
Environmental exposure range: –20 °C to 287 °C [0 °F to 550 °F]
2450CM/2455RM 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)
