3153 00010021 Datasheet PDF - Honeywell

●The 3153 Series is a single-pole, single-throw switch activated by a snap-action bimetal disc. The case is laser welded to form a hermetically-sealed steel housing, with a glass-to-metal seal at the terminal junction. The low profile and compact design allow use in most applications that require miniaturization. Temperature calibrations are pre-set at the factory and each unit is thermally and mechanically inspected. It is available to open or close on temperature rise.
