The M3056 current detection relay with a normally closed (NC) contact has been specifically designed for the effective protection of electrical installations, monitoring of machinery operation and the automation of both industrial and domestic systems.\u003cbr\/\u003e\u003cbr\/\u003eThis device operates on the principle of contactless inductive sensing. It uses an internal transformer for measurement, so the phase conductor being monitored simply needs to be threaded through a 10 mm diameter hole in the device’s housing. There is no need for any complicated series wiring or for cutting the power cable. A major advantage is that the device does not require an external power supply, as it is powered inductively directly from the current passing through the receiver.\u003cbr\/\u003e\u003cbr\/\u003e\u003cbr\/\u003ePrinciple of operation:\n\nUsing a precision multi-turn potentiometer, you can easily set the required current threshold (within the range of 0.2 to 30 A AC).\u003cbr\/\u003eOvercurrent: As soon as the current flowing through the circuit exceeds the limit you have set, the output contacts K1–K2 open immediately (normally closed (NC) contact logic).\u003cbr\/\u003eCurrent drop: If the current value falls below the set limit, contacts K1–K2 return to their original state and remain closed.\u003cbr\/\u003e\u003cbr\/\u003e\u003cbr\/\u003eKey advantages of the M3056 current relay:\n\n-Fully autonomous operation: Operates without any auxiliary power supply – saving space in the control cabinet and simplifying cabling.\u003cbr\/\u003e-High accuracy and speed: With a measurement accuracy of 1% and a lightning-fast response time of up to 200 ms, it can react immediately to critical conditions.\u003cbr\/\u003e-Safe inductive sensing: Galvanic isolation of the measured circuit from the switching contact ensures maximum safety.\n-High overload resistance: The relay can withstand short-term maximum overloads of up to 100 per cent.\u003cbr\/\u003e-Low hysteresis: Highly stable switching thanks to low hysteresis (? 2 per cent), which prevents unwanted contact oscillation at values close to the set limit.\n\n\nTechnical specifications:\u003cbr\/\u003e\u003cbr\/\u003e-Model: M3056\u003cbr\/\u003e-Output type: Normally Closed (NC) contact, terminals K1–K2\n-AC input current range: 0.2 to 30 A AC\n-Threshold adjustment: Multi-turn potentiometer\u003cbr\/\u003e-Power supply: No external power supply (inductively from the measured conductor)\n-Rated contact load: ? 0.3 A at 240 V AC\/DC Contact resistance (K1–K2): 4 ohms.\u003cbr\/\u003e-Leakage current: ? 0.1 A\n-Measurement accuracy: 1 %\n-Hysteresis: ? 2 %\n-Response time: ? 200 ms\n-Conductor hole diameter: 10 mm\u003cbr\/\u003e-Protection rating: IP30\n-Operating temperature: -20 °C to +60 ?\n-Dimensions: 65 × 25 × 47 mm\u003cbr\/\u003e\u003cbr\/\u003eProvide your electrical installations and machinery with professional, autonomous monitoring. With the M3056 current detection relay, you gain an accurate and reliable guardian against overloads that requires not a single watt of external power to operate.","brand":"TIPA","offers":[{"title":"Default Title","offer_id":55211266507090,"sku":"09830398","price":3930.08,"currency_code":"HUF","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0954\/9624\/1490\/files\/09830398.jpg?v=1792994596","url":"https:\/\/tipa.eu\/en-hu\/products\/m3050-ac-current-relay-module-nc-make-contact-adjustable-0-2-30-a","provider":"TIPA","version":"1.0","type":"link"}
