Figure 10. Series 2455RBV Overmolded Automatic Reset Thermostats
The 2455RBV Series has a temperature-sensitive bimetal
disc, electrically and thermally isolated from the switch that
is used to actuate the normally closed contacts. The
contacts open when surface or ambient temperatures
increase to the operating set point of the calibrated bimetal
disc. The entire switch is enclosed in a phenolic or ceramic
housing; the bimetal disc is retained by a metal heat-
conducting end cap. The unit is then encapsulated in epoxy.
This series is UL/CSA and European approved.
Potential applications include:
• Automotive
• Industrial equipment
• HVAC
