Designed for automatic shut-off of pumps with a capacity of up to 1.5 kW, in the absence of water in the system.
When the pressure in the water supply system is less than 0.15-0.9 bar (depending on the setting), the pump power is turned off, and protection against breakage as a result of working without water (dry running).
Connection diameter 1/4" external thread.
Adjustment range 0.15-0.9 bar
Power supply parameters 220V /50Hz
Protection class IP44 (protection against ingress of objects more than 1 mm and protection against splashes of water falling in any direction)
