Adjustable current detection: accurately set the operating/trip current between 0.2 A and 30 A AC to match different loads and protection requirements. Fast, reliable response: instantaneous detection and reaction for quick interruption or signaling of overcurrent events. Durable, contactless switching: high-performance MOS-tube electronic switch provides reliable, wear-free operation without mechanical contacts. Simple installation: self-powered by the sensed current — no external power supply required — reducing wiring and setup time. What this product does for you Prevents equipment damage and nuisance trips by letting you precisely match the activation current to the appliance or circuit. Reduces maintenance and downtime thanks to a contactless switching element that avoids contact wear and arcing. Saves installation time and complexity because no separate power source is needed. Key attributes Function: adjustable AC current detection and contactless switching. Operating range: 0.2 A to 30 A AC (adjustable). Switching technology: electronic MOS-tube (contactless) switch for high reliability. Power requirement: no external supply required; device is powered from the measured current. Compatibility: suitable for AC circuits and loads within the specified current range. Typical applications Home appliances and lighting: protect and control washing machines, dishwashers, lighting circuits or other household AC loads by setting an appropriate activation threshold. Motors and HVAC equipment: detect and respond to motor startup or overload conditions in fans, pumps, and HVAC units within the 0.2–30 A range. Industrial control and automation: integrate into control panels for machine protection, fault detection, or automatic load shedding where precise AC current sensing is needed. Installation and use notes Set the action current to match the protected load; ensure the chosen value falls within 0.2–30 A AC. Because the switch is contactless and self-powered, wiring is simplified, but observe correct orientation and safe wiring practices for AC circuits. Verify compatibility with the specific application’s voltage and load characteristics before installation. Reliable, adjustable AC current detection with fast, contactless switching — designed to simplify installation and extend service life in a wide range of AC applications.
