With a switching\ncapacity of 50A and a safe 24V AC control voltage, it acts as a perfect\ninterface between your low-voltage automation (e.g. Loxone, KNX) and power-\nhungry terminals. Thanks to the 2NO+2NC contact assignment, complex switching\nand locking scenarios can be realized that are essential for modern home power\nmanagement. Why Wengart is the first choice in 50A applications: No net\nhumming: Specially designed for use in the living area - vibration-free and\nsilent in operation. Maximum safety: flame retardant housing and solid\nreinforced terminals prevent heat build-up under continuous load. Versatility:\nIdeal for load shedding in PV systems and electric car charging stations.\nTechnical data (specifications): characteristic specification contact\nassignment 2 N\/O contacts (NO) + 2 openers (NC) coil voltage AC 24 V (50\/60\nHz) rated current (In) 50 A (AC-7a \/ household applications) Width 54 mm (3\ngraduation units \/ 3 TE) Frequently asked questions (FAQ): Q: Why is this\nprotector so wide (54mm)? A: With a current of 50A, heat is generated. The\nwidth of 3 TE (division units) is a quality feature that ensures sufficient\ncooling surfaces and safety to avoid overheating in the control cabinet. Q: I\nwant to lock my wallbox and heat pump against each other. Is that possible? A:\nYes, that's exactly what the 2NO+2NC configuration is perfect. You can run the\ncircuit of the heat pump via the opener (NC). As soon as the wallbox is\nactivated via the closer (NO), the contactor automatically disconnects the\nheat pump to prevent overloading the house connection. Q: Can I control the\ncontactor with a Shelly Uni or a 24V transformer? A: Yes, if your control unit\nsupplies 24V AC this contactor is the ideal addition to your smart home\ncontrol.\u003c\/p\u003e \n\n\u003ch3\u003eProduct Features\u003c\/h3\u003e\n  \u003cul class=\"a\"\u003e\n         \u003cli\u003eSpecialized 24 V AC control voltage: IMPORTANT: The coil of this high-performance contactor is powered by 24 V AC current (AC). Ideal for safe control by smart home systems or PLCs. Note: A direct connection to 230 V leads to the immediate destruction of the coil\u003c\/li\u003e\n         \u003cli\u003eMassive 50A switching capacity: designed for heavy loads. With 50A rated current, the WCT-50 offers enormous reserves for controlling heat pumps, large instantaneous water heaters or for load switching in photovoltaic storage systems.\u003c\/li\u003e\n         \u003cli\u003eIntelligent 2NO + 2NC switching logic: equipped with 2 N\/O contacts and 2 openers.
