KTO511 compact mechanical bimetallic thermostats designed for electrical cabinet temperature control. KTO511 is normally‑closed for heater control, while KTS511 is normally‑open to trigger cooling fans.

With a durable snap‑action contact structure, long service life and wide voltage compatibility, these small DIN‑rail thermostats deliver reliable temperature regulation inside enclosures, preventing overheating or condensation.

The units have passed salt spray and 4000‑meter high‑altitude tests, suitable for harsh coastal and plateau working environments. Certified with CE & RoHS and backed by a 5‑year warranty, they are widely matched with cabinet heaters and cooling fans.
