- Reduced installation time by 50 % with PUSH IN connection technology
- Maximum switching capacity 16 A, 230 V
- Protection type frostTHERM-AT: IP40 frostTHERM-DR: IP20 JUMO frostTHERM-AT/-DR Surface-mounted or DIN rail thermostat
Description
The frost protection thermostat is used for temperature monitoring in ventilation and air conditi- oning systems to prevent damage caused by frost. It has a low switching differential and a high reproducibility. Reset occurs automatically (STW) or manually (STB). High application flexibility and the latest connection technology are the essential equipment fea- tures of this thermostat series. The thermostat case is suitable for all common installation types such as wall, pipe, and DIN rail mounting. The JUMO frostTHERM-DR type is a specific variation with a special case bottom section for DIN rail or wall mounting. This allows easy mounting on mounting rails TH35 according to DIN EN 60715 (e.g. in control cabinets). This version conside- rably reduces the mounting time. The PUSH IN terminal technology allows the connection wires to be only inserted into the con- tact point up to the stop. No tool is required for connecting the wire or braid with the ferrule, the- reby increasing safety during wiring. As a re sult, the costs and time required for connection is considerably reduced compared that of the conventional screw terminal. The PUSH IN terminal technology allows direct switching of loads up to 16 A at AC 230 V. The installation costs can be reduced further because a contactor is not required.

Switching function Safety temperature monitor STW Safety temperature limiter STB Technical data Electrical data If the probe line falls below the entered setpoint value over a length of 15 cm with 3 m, 30 cm with 6 m, and 40 cm with 12 m, then electrical circuit 1 to 2 is opened while electrical circuit 1 to 4 is closed due to the changeover func tion. When the temperature rises, the microswitch is automati- cally switched back to its original position. If the measuring system is destroyed (i.e. if the expansion fluid escapes) the pressure in the diaphragm drops and permanently opens electrical cir- cuit 1 to 2 and closes electrical circuit 1 to 4. In the event of a temperature drop, the safety temperature li miter automatically locks and can only be unlocked manually once t he temperature has risen again. If the measuring system is destroyed (i.e. if the expansion fluid escapes), the pressure in the diaphragm drops and permanently opens electrical circuit 1 to 2 and closes electrical circuit 1 to 4.
