Overview

The Hammond Manufacturing SKT011409NC is a normally closed thermostat designed for precise air temperature control in industrial enclosures. This unit features a bimetal sensor with an adjustable temperature range of 30-140°F and a switching difference (hysteresis) of ±4°F. It is specifically designed for controlling heaters and heater fans, where the contact opens when rising temperatures reach the set point, shutting the heater off. The thermostat is easily installed via clip mounting on a 35mm DIN rail and utilizes 2-pole screw terminals compatible with AWG 14 (2.5 mm²) conductors. With a voltage rating of 120VAC/240VAC and current ratings of 15A @ 120VAC and 10A @ 240VAC, it also supports 30W DC switching. Constructed from flame retardant UL94VO plastic, it offers IP20 protection. The SKT011409NC is UL Recognized Component and CE marked, ensuring compliance and reliability in applications such as HVAC, refrigeration, and machinery enclosures requiring low-temperature protection or heater control. Its compact dimensions (2.8" H x 1.5" W x 1.4" D) make it suitable for space-constrained environments.
