Honeywell Bi-Metallic Thermostat, Opens at +100°C, Closes at 85°C, +150°C Max, NC, Automatic Reset, Through Hole Mount

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.

UL recognised component, CSA Certified

If you have precise temperature-control requirements, opt for this bi-metallic thermostat from Honeywell. It maintains temperature settings to a very high level of accuracy. This SPST (single pole, single throw) snap-action switch is normally closed (NC) and is compatible with 250 V AC circuits. The switch opens when the temperature rises to +100°C and automatically resets (closes) at 15°C below the nominated operating temperature (+85°C).

• Quick connecting terminal type for ease of installation
• Robust body made from phenolic resin with stainless steel end cap assures a long operating life
• Can tolerate high-current applications, thanks to the 15 A-rated contacts
• Broad operating temperature range of 0°C to +150°C for use in various demanding industrial situations

• Automotive industry
• Major appliances
• Heat and smoke detectors

Bi-metallic thermostats are operated by discs made of two metals. When the temperature falls or rises, these metals respond differently from each other, but in a predictable and consistent manner. This causes the disc to flex, which opens or closes the contacts and operates the switch.
