Bi-Metallic Thermostat
Snap action bi-metallic disc operates an SPST contact which is electrically isolated from the mounting bracket.
All types reset when the temperature falls to nominally 15° below operating temperature.
• Phenolic body with stainless steel end cap.
• 1/4in tab termination.
• Contacts are rated to 250 Vac 10A with a maximum contact resistance of 50 mΩ.
• Dielectric strength of 2000 Vac.
• N/C types open on temperature rise.
• N/O types close on temperature rise.

Honeywell Bi-Metallic Thermostat, NC, Opens at +150°C- 2455RA Series -2455R 82-235 L150C
This bi-metallic thermostat from Honeywell is suitable for highly accurate temperature regulation across various commercial applications. The SPST (single pole, single throw) snap-action switch is normally closed and will open when the temperature rises to +150°C. It automatically resets (closes) at 15°C below the nominated operating temperature (+135°C). The unit has a high dielectric strength of 2000 V AC, so it can handle high voltages without failing or breaking down. For safety, the SPST contact is electrically separated from the mounting bracket.
Features and Benefits
