Chromalox TS3KIT Thermostat Kit is a single-pole thermostat assembly rated for 277 VAC and capable of switching up to 25 A, designed for Chromalox heating applications that require a simple on/off temperature control. The kit is identified by model TS3KIT (also listed as TS‑3‑KIT) within Chromalox’s thermostat kit lineup. Catalog listings indicate the TS3KIT has been discontinued by the manufacturer, so current stock is limited and available primarily through secondary channels; some listings describe it as new-in-box. When found, this thermostat kit provides a direct replacement option for installations that originally called for the TS3KIT.
