DIN rail Zigbee smart switch Nous D3Z, single-channel 25 A for electrical distribution

Nous D3Z is a DIN-rail Zigbee smart switch designed for installation in electrical distribution boards. Rated for 25 A on a single output channel, this compact module enables remote on/off control of lighting circuits and single-channel loads via Zigbee-compatible hubs and controllers. The device is intended for residential and light-commercial installations where DIN-rail mounting and integration with a smart home ecosystem are required.

Advantages

The device provides reliable single-channel switching with a high current rating suitable for common lighting loads and small appliances. Its DIN-rail form factor saves panel space and simplifies wiring in distribution boards. Integration through Zigbee enables remote control, scene implementation and compatibility with a range of Zigbee hubs. The compact design supports standard distribution board layouts and helps centralize control of circuits without altering existing wiring topology.

Suitable for

• Remote switching of lighting circuits in homes and apartments
• Control of single-channel loads such as small motors, fans or heaters within rated limits
• Integration into Zigbee-based home automation scenes and schedules
• Use in electrical distribution boards where DIN-rail mounting is required

Key specifications

• Mounting: DIN-rail compatible enclosure for distribution boards
• Switching channels: single-channel output
• Maximum current rating: 25 A per channel
• Communication protocol: Zigbee wireless control
• Control functions: remote on/off switching, support for scenes and automation via Zigbee hub
• Application scope: lighting circuits and single-channel resistive or inductive loads within specified current

How to use

Install the module into a standard DIN-rail inside the distribution board and connect incoming supply and outgoing load conductors according to local electrical codes. Pair the switch with a Zigbee-compatible hub or coordinator following the hub manufacturer's pairing procedure to enable remote control and automation. After pairing, use the hub’s app or automation platform to configure on/off schedules, scenes, or integrate the device into existing automation routines. Ensure the connected load does not exceed the 25 A rating and verify proper protective devices are in place.

Usage recommendations

Use the Nous D3Z with appropriate circuit protection (breakers or fuses) sized for the feeding conductor and the connected load. For inductive loads such as motors, confirm inrush current and ensure the switch and upstream protection can handle short-duration peaks. Follow national electrical safety standards and, if unsure, engage a qualified electrician for installation and commissioning. Regularly check connections and enclosure conditions during maintenance intervals.
