DIN rail Zigbee smart switch Nous D2Z, single-channel 20A, DIN-mount

Nous D2Z is a DIN-rail Zigbee smart switch designed for single-channel control of lighting and other electrical circuits in distribution enclosures. Rated for 20A switching, this DIN-mount device integrates into Zigbee-based smart home systems to enable remote on/off control, schedule-based operation and scene activation. The compact enclosure fits standard DIN rails and is intended for residential and light-commercial electrical panels where reliable remote control and automation are required.

Advantages

The device supports Zigbee communication for robust mesh networking and interoperability with compatible hubs and controllers. With a 20A switching capability, it handles most lighting loads and small appliances commonly found in homes and small businesses. Its DIN-rail form factor simplifies installation in electrical cabinets and distribution boards while keeping wiring tidy and accessible. The switch offers remote control and scheduling functions without the need to change existing wall switches or wiring layouts.

Suitable for

• Remote control of lighting circuits in homes and apartment distribution panels
• Automation of hallway, stairwell and utility room lighting
• Integration with Zigbee-based scenes and schedules for energy management
• Control of small resistive and inductive loads within the 20A rating

Key specifications

• Mounting: standard DIN-rail enclosure compatible with distribution cabinets
• Channels: single-channel switching output
• Maximum switching current: 20 A
• Control interface: Zigbee wireless communication for remote control and automation
• Application: designed for lighting and general-purpose circuit switching

How to use

Install the smart switch on a standard DIN rail inside an electrical distribution enclosure and connect line and load conductors according to local electrical codes. Pair the switch with a Zigbee gateway or compatible hub following the hub manufacturer’s pairing procedure. Once paired, assign the device to a room or group and configure on/off controls, schedules and scenes through the Zigbee controller app. Ensure the connected load is within the 20A rating and that wiring and protection devices are correctly sized for the circuit.

Usage recommendations

Use the device in electrical systems with appropriate circuit breakers or fuses and verify compatibility of loads that have high inrush currents. For reliable Zigbee communication, place the gateway within range or use additional Zigbee routers/repeaters to extend mesh coverage. Follow local electrical regulations and consult a qualified electrician for installation if you are not experienced with mains wiring.
