KTS013 DIN Rail Normally Open Thermostat 0-60C
Key Specifications
The KTS013 normally‑open mechanical bimetal thermostat is a compact DIN‑rail temperature controller designed for cooling control inside electrical cabinets. It automatically activates cooling fans or alarm devices once ambient temperature exceeds your preset value.
Built for industrial enclosures, it prevents overheating damage to electronic components and supports stable operation within harsh temperature environments of ‑45℃ ~ +80℃.

What Buyers Ask Before Inquiry
Both are normallyu2011open cooling thermostats with 0u201160u2103 range and DIN rail installation. KTS013 has a shorter body height of 60mm (KTS012 is 75mm). Choose KTS013 when your cabinet has limited vertical installation space.
The switching differential is factory fixed and nonu2011adjustable. This design prevents frequent fan cycling caused by tiny temperature swings and reduces component wear. If you need a different differential, please contact us for customized models.
Snapu2011action contact realizes rapid on/off switching. It eliminates slow, unstable contact closure, reduces electric arcing, protects connected fans and extends the overall service life of the thermostat.
