Description

The AT 120 HR HY is a heavy duty float level switch designed for aggressive liquids. This float is encased in a HR HY (High Resistance) press-vulcanised housing, which ensures a double waterproof. The AT 120 HR HY can be connected directly to pumps up to 1.5 HP or through a relay if working with high power pumps. Its wide switching angle of 120º protects the pump´s engine and the electrical panels from jerking, specially when dealing with very agitated liquids.
