Description
The Fenwal 17021-0 Thermoswitch is a precision cartridge-type temperature controller designed for accurate thermal regulation in industrial applications. Utilizing the principle of differential thermal expansion between a brass shell and an internal strut assembly, it opens or closes electrical contacts based on temperature changes, providing reliable on/off control without external power. Adjustable from 100°F to 400°F, this model features a close-on-rise contact configuration and is ideal for use in injection molding machines, platens, heat exchangers, and process equipment where precise temperature monitoring is critical. Benefits include high accuracy (±5°F setpoint), rugged brass construction for durability in harsh environments, and easy installation via threaded mounting. Compared to modern digital thermostats, it offers simplicity and no need for calibration tools, though it lacks remote monitoring capabilities. Drawbacks may include limited adjustability range and mechanical wear over time. This unit appears new old stock, complete with original packaging and instructions, making it suitable for legacy system replacements or specialized setups.
