Looking for a manual reset bi-metallic thermostat? This option from Honeywell is designed for applications where the slightest over temperature can be critical and where there's a need for highly accurate temperature readings. Its compact size and combination of metals allow it to respond rapidly to temperature changes. The unit has an SPST (single pole, single throw) construction, so it acts as an on-off switch. It's actuated by a snap-action bi-metal disc that's temperature-sensitive. This triggers the normally-closed (NC) contacts when surface or ambient temperatures reach the operational set point of +70°C.

• High-capacity 10 A rating
• Factory calibrated for standard performance
• Silver/nickel alloy contacts for high performance
• Phenolic housing for durability
• Quick-connect terminals for ease of installation

• Heating, ventilation and air-conditioning equipment
• Office automation products
• Medical equipment

Honeywell 2455RM Series thermostats are designed to cater for a wide range of industrial and commercial settings in both hot and cold environments. This device will safely operate between 0°C and +150°C.
