Wengart 25A AC Contactor 4-Pole 4NO, AC 120V Coil Modular DIN Rail Mount Magnetic Contactor for Smart Home, EV Charging, HVAC and Multi-Circuit Lighting Control, White

Wengart WCT-25 4-Pole Contactor: High-Performance Automation for Modern Electrical SystemsThe Wengart WCT-25 4NO Modular AC Contactor provides a reliable solution for managing high-power electrical loads in residential and light industrial environments. Whether you are automating a large-scale lighting array or installing an EV charging circuit, this 4-Pole 25A Contactor delivers the switching capacity and durability required for 24/7 energy management.Key Technical Features & Value:4-Pole 4NO Configuration: Simultaneously switch up to 4 separate 120V lines or multiple phases. This is particularly useful for applications requiring the total disconnection of both hot and neutral lines for enhanced safety.Optimized 120V AC Coil: Specifically wound for standard North American residential voltages, ensuring seamless compatibility with thermostats, smart switches, and digital timers.Superior Thermal Performance: The advanced coil design generates significantly less heat compared to generic contactors, preventing the "hot-to-touch" issues often found in enclosed panels.Visual Monitoring: The built-in status window provides a mechanical real-time update on the contactor’s state, allowing for quick troubleshooting without specialized tools.Category Applications & Usage Scenarios:As a versatile Magnetic Contactor and Motor Starter, the WCT-25 is an essential component for:Smart Home Infrastructure: Safeguarding smart switches from high inrush currents of motors or extensive LED drivers.HVAC Management: Controlling electric heaters, ventilation systems, and air handling units.EV Charging Solutions: Serving as a safety disconnect or control relay for Level 1 or Level 2 EVSE units.Outdoor & Landscape Lighting: Managing multiple zones of high-power floodlights or architectural lighting.Product Specifications Table: Attribute Detailed Specification Model Number WCT-25 (4-Pole) Rated Current (In) 25A (AC-7a) / 9A (AC-7b) Coil Voltage (Us) AC 110V-120V, 50/60Hz Contact Config 4NO (Normally Open) Installation Standard 35mm DIN Rail Mount Durability 100,000+ Electrical Cycles Frequently Asked Questions (FAQ):Q: Why should I choose the WCT-25 over generic industrial switches? A: Generic industrial contactors often produce a loud, persistent 60Hz humming noise and run extremely hot, making them unsuitable for indoor residential use. The Wengart WCT-25 is engineered for domestic environments, featuring high-precision magnets and efficient coils that minimize vibration and heat buildup while maintaining a heavy-duty 25A rating.Q: Can a 120V coil control a 240V device? A: Yes. The Coil Voltage (120V) is the signal that activates the magnet, while the Contacts (Load) are rated to handle up to 400V. You can use a standard 120V wall timer to switch a 240V water heater or pool pump safely.Q: Is this contactor compatible with my breaker box? A: This unit is designed for 35mm DIN rail mounting. It is a standard fit for smart home enclosures and modular distribution boards. If you have a traditional US-style load center, you will need a small section of DIN rail installed to mount this device.

• Versatile Multi Circuit Load Management: The WCT-25 features a 4-pole 4NO (Normally Open) configuration, allowing the simultaneous switching of up to four independent circuits. With a robust 25A rating per pole, it is an ideal solution for complex electrical setups, such as controlling multiple LED lighting zones, irrigation systems, or managing high-wattage residential appliances through a single control signal.
• Energy Efficient Low Heat Coil: Equipped with a precision-engineered AC 110V-120V coil, this contactor is designed for stable and continuous duty. The optimized magnetic circuit significantly reduces holding power consumption and minimizes heat dissipation. This ensures the unit remains cool during extended engagement, protecting neighboring components on your DIN rail from thermal stress.
• Reliable Smart Home Ecosystem Bridge: Acts as a high-capacity intermediary relay between low-power smart controllers and heavy-duty loads. By using a standard smart plug or WiFi switch to trigger the 120V coil, the contactor safely manages the 25A high-current load. This protective setup prevents internal relay burnout in smart devices and extends the service life of your home automation system.
• Compact Modular Space Saving Design: The streamlined 36mm width (2-module size) integrates easily into standard 35mm DIN rail distribution boards. This compact footprint is perfect for residential electrical panels where space is limited. It includes a clear mechanical status indicator window, providing an instant visual confirmation of the contact position without removing the terminal covers.
• High Strength Safety Certified Materials: Constructed with high-grade silver alloy contacts for superior electrical conductivity and oxidation resistance, rated for over 100,000 electrical cycles. The housing is made from flame-retardant (UL94-V0) polycarbonate, providing industrial-strength durability for HVAC, EV charging stations, and power automation. Please verify your control voltage is 120V before purchase.
