KTS111 (also named KTS011) is a compact normally‑open bimetallic mechanical thermostat designed for enclosure cooling control. Adopting bimetal temperature sensing element and snap‑action contact, it realizes automatic fan control for electrical cabinets.

Made of flame‑retardant PC housing, this tiny thermostat features 0~60℃ adjustable temperature range. It clips onto standard 35 mm DIN rail for quick installation. With long service life exceeding 100,000 switching cycles and CE & RoHS certification, it is widely used to activate filter fans or alarm devices and prevent control cabinets from overheating.
