As part of ABB’s industrial automation portfolio, the KTO011 supports a wide temperature adjustment range (-10°C to +50°C) with a switching hysteresis of ±4K, ensuring stable thermal control with minimal temperature fluctuations 17. Its robust thermostatic bimetal sensor guarantees >100,000 operating cycles, while the IP20-rated housing (UL 94 V-0 plastic) protects against dust and mechanical impacts 116. The module’s compact dimensions (60 mm × 33 mm × 43 mm) and 35 mm DIN rail mounting simplify installation in space-constrained environments, while color-coded temperature dials enable quick visual verification of setpoints 18.
Key technical features include a high switching capacity (250V AC/10A resistive) and compatibility with both AC and DC power supplies, making it suitable for diverse industrial applications. The KTO011 also incorporates safety mechanisms such as thermal overload protection and contact resistance monitoring, ensuring long-term reliability even in harsh conditions 121. By maintaining consistent temperatures in enclosures, this thermostat helps prevent component degradation, reduce energy consumption, and extend the lifespan of connected equipment.
