Aquastop plug-in device SHT 226 with mains plug
Mini float switch (including control cable 2.5 m)
Note: To attach the float switch, order the mounting bracket (Art. No. 300787) at the same time
The SHT 226 reliably protects devices and rooms from damage caused by water or other liquids.
Unlike the SHT 216, this Aquastop doesn't react to tiny drops , but only when liquid accumulates at least 4 cm high . This is ideal when water accumulates in places you can't immediately see or reach—for example, in pumping stations, tanks, or basements.
How it works:
🏠 Lifting systems for washing machines or dishwashers: If the pump is defective, the water in the lift tank rises. The SHT 226 shuts off the machine before water damage occurs.
🛢️ Heating oil tanks or lubricating oil containers: Alarms in case of overfilling or leaks.
🚿 Water storage tanks or rainwater systems: Stop pumps or warn before water overflows.
💧 Basements or utility rooms: Protects against backflow, burst pipes or leaking water.
Extending the sensor cable: 2.5 m long as standard, the cable can be extended up to 50 m using a LIYY cable (max. 2 x 0.14 mm²). Connections are made via terminals or can be customized to a specific length ex works upon request.
Versatile use: Thanks to the mini float switch, the SHT 226 detects liquid levels from 4 cm high – perfect for heating oil tanks, lubricants or other non-conductive liquids.
Note: LIYY cables are temporarily waterproof, flame-retardant, self-extinguishing, low-adhesion, and largely resistant to oils, greases, coolants, and lubricants.
