The temperature controls RD-1 i RD-2 are for use in environmental temperatures from -20°C to 55°C. The temperature controls are not encased and are designed for devices of Class 0I and I. All controls have 6,3 mm tabs according to DIN 46244 and optional earth tab. The cut-out temperature is adjusted by the dial shaft. Turning the dial shaft clockwise adjusts higher cut-out temperature. These controls are remote units.

These controls can be mounted in any position with two M4 screws. Care should be taken that a possibly best thermal contact exists between bulb and the controlled medium. The earth cable should be connectedwith the marked tapped M4 hole.

The RD-1 and RD-2 temperature controls are temperature-operated switches. They are designed for controlling the work of electrical heaters. They cut-out the circuit on temperature increase and automaticly cut-in when temperature drop is higher than temperature differential. Type RD-1 code number 0025-2333 have change-over contact.
