Wengart Humm-free installation contactor 50A AC 24V - 2NO + 2NC (2 N/O contactors, 2 openers) - 54 mm width (3 TE) - silent protection for heat pumps, PV storage & wallbox control - WCT-50
Wengart Humm-free installation contactor 50A AC 24V - 2NO + 2NC (2 N/O contactors, 2 openers) - 54 mm width (3 TE) - silent protection for heat pumps, PV storage & wallbox control - WCT-50
Wengart WCT-50 Silent - Maximum power for your intelligent load management The Wengart WCT-50 is a powerhouse among installation protectors. With a switching capacity of 50A and a safe 24V AC control voltage, it acts as a perfect interface between your low-voltage automation (e.g. Loxone, KNX) and power- hungry terminals. Thanks to the 2NO+2NC contact assignment, complex switching and locking scenarios can be realized that are essential for modern home power management. Why Wengart is the first choice in 50A applications: No net humming: Specially designed for use in the living area - vibration-free and silent in operation. Maximum safety: flame retardant housing and solid reinforced terminals prevent heat build-up under continuous load. Versatility: Ideal for load shedding in PV systems and electric car charging stations. Technical data (specifications): characteristic specification contact assignment 2 N/O contacts (NO) + 2 openers (NC) coil voltage AC 24 V (50/60 Hz) rated current (In) 50 A (AC-7a / household applications) Width 54 mm (3 graduation units / 3 TE) Frequently asked questions (FAQ): Q: Why is this protector so wide (54mm)? A: With a current of 50A, heat is generated. The width of 3 TE (division units) is a quality feature that ensures sufficient cooling surfaces and safety to avoid overheating in the control cabinet. Q: I want to lock my wallbox and heat pump against each other. Is that possible? A: Yes, that's exactly what the 2NO+2NC configuration is perfect. You can run the circuit of the heat pump via the opener (NC). As soon as the wallbox is activated via the closer (NO), the contactor automatically disconnects the heat pump to prevent overloading the house connection. Q: Can I control the contactor with a Shelly Uni or a 24V transformer? A: Yes, if your control unit supplies 24V AC this contactor is the ideal addition to your smart home control.
Product Features
- Specialized 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
- Massive 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.
- Intelligent 2NO + 2NC switching logic: equipped with 2 N/O contacts and 2 openers. This configuration allows complex locking circuits perfect for prioritizing a wallbox, for example, while automatically disconnecting other large consumers.
- Humm-free silent technology: Acoustic comfort despite high performance. Our optimised magnetic structure eliminates the typical 50Hz net humming. The contactor works whisper-quiet and is therefore ideal for installation in residential buildings.
- Robust design on 3 TE (54 mm): the generous width of 54 mm guarantees excellent heat dissipation at high current loads. Equipped with reinforced clamps for secure cable connections and maximum fire safety in the control cabinet.
