STEGO STS011 Thermostat

STS011 is a compact, normally-open thermostat switch from STEGO that closes its NO contact as the cabinet temperature rises, making it ideal for triggering enclosure cooling or heat-exchanger systems or signaling inputs in STEGO enclosures. This mechanical thermostat uses a bi‑metal sensor and is designed for screw-terminal mounting with IP20 protection. The standard switching range is +0°C to +60°C (32°F to 140°F), with adjustable thumbwheel variants available under part numbers such as 01116.0-00 and 01116.9-00 that let you set the trip point without external sensors. Typical load ratings for the NO STS011 family include up to 10 A at 250 VAC for the screw-terminal versions, with other STS011 variants offering different ratings and load configurations as specified in the datasheets. Common applications include regulating filter fans and heat exchangers in electrical cabinets and other control panels, or serving as a simple temperature-triggered switch in signaling circuits. The form factor is designed to fit compact spaces, delivering straightforward, maintenance-friendly temperature control for enclosure cooling and condensation prevention.
