INTRODUCTION
®
C.S.A. approved control device which features a mechanical
snap action switch. Controllers are available for operation on
temperature with fixed or variable differential. Also, manual reset
types are available for operation on increasing or decreasing
temperature. The manual reset types remain tripped until reset
by pressing a button on the top of the enclosure. The standard
electrical switch is SPDT and is available with various electrical
characteristics. Two SPDT switch elements mounted together
are available except on variable deadband and manual reset
types. Bulb material is stainless steel.
The Ashcroft snap action temperature switch is furnished in the
standard NEMA 4/4X and explosion proof NEMA 7 and 9 enclo-
sure styles. Both enclosures are epoxy coated aluminum castings.

left with internal components exposed. During installation insure
that covers are in place and conduit openings are closed except
when actually working on the control. Good piping practice re-
quires the use of a thermowell for installation where pressure
may be applied to the thermal system. The thermowell provides
protection against physical damage as well as corrosive effects
of media flow. Use of a thermowell also facilitates removal of the
bulb from the process line without disturbing the process. Stan-
dard thermowell materials include brass, steel and stainless
steel; other materials are available upon request. Selection
should be based on corrosion resistance requirements and
process pressure.
