The Trafag AS33 (650 2502 402 19) is a thermostat used within shipboard control systems, covering a temperature range of -30 to +30 °C. As a temperature-operated switch, it gives control circuits an on/off signal tied to the temperature at the sensing point, so connected equipment can be started, stopped or alarmed as conditions change. The power supply rating is given as 250 V AC/15(1.25) A and 30 V DC/6(1.5) A, and the unit carries the -30T40 marking. This thermostat is supplied in New Open Box condition.
