## Long description

Shelly 4CD 230V is a 4-channel decoupler designed for DIN-rail mounting that provides isolated relay switching for four separate circuits. Intended for integration into electrical panels and automation systems, it allows remote or centralized control of lighting, small motors and other 230V loads while keeping each channel electrically isolated. The compact form factor fits standard distribution boards and supports retrofit and new-build installations where reliable switching and circuit separation are required.
Advantages
The device offers four independent relay channels in a single DIN-mount enclosure, enabling installation density and simplified wiring. Electrical isolation between channels reduces interference and enhances safety for multi-circuit setups. The unit supports reliable on/off switching of 230V loads and is suited for integration with building automation systems. Its compact dimensions and DIN-rail compatibility make it convenient for electrical cabinets and professional installations.
Suitable for
Centralized control of lighting circuits in homes, offices and commercial spaces
Switching small inductive loads such as fans or pumps with appropriate wiring
Integration into automation panels and control systems
Retrofit projects where DIN-rail mounting and circuit isolation are needed
Key specifications
Number of channels: 4 independent relay outputs
Supply and switching voltage: 230 V AC
Mounting type: DIN-rail compatible enclosure
Output type: isolated relay contacts per channel
Application: switching of resistive and small inductive loads at mains voltage
Form factor: compact module designed for electrical distribution panels
How to use
Mount the unit on a standard DIN rail inside the electrical panel and connect mains power according to local electrical codes. Wire each load to the respective relay output, observing correct phase and neutral wiring practices and ensuring appropriate load ratings and protection devices (fuses or breakers) are in place. Integrate control signals or automation wiring to the unit as required by the control system. Commission the channels one by one, verifying correct switching behavior and isolation between circuits before putting the system into regular operation.
Usage recommendations
Use the decoupler with loads within its specified voltage and current limits and include dedicated overcurrent protection for each circuit. Ensure installation and wiring are carried out by a qualified electrician and follow local regulations. Avoid connecting high inrush or high-power motors without evaluating contact ratings and adding appropriate protections such as soft-start devices or contactors when necessary.
