Temperature Relay RT-303

RT-303 is intended for the pump blocking systems to switch the electric circuits, including the spark-proof ones, when the temperature of the bearing unit casing temperature reaches the pre-set value.

The temperature relay is used in the automated control systems and temperature protective systems.

The relay is manufactured in two versions differentiated by the plunged part length.

The relay is adjusted within the range from +50 to +90°C (a special order can be made for any value within the range from -10 to +200°C).
