Solid-state relay for AC load switching

The Hanyoung Nux HSR-3D304Z is a solid-state relay designed to switch AC loads without mechanical contacts. It uses semiconductor switching to provide silent operation and extended service life compared to electromechanical alternatives. The unit is supplied new in a single pack.

Suitable for panel-mount control circuits

This relay suits electricians and maintenance engineers fitting or replacing solid-state switching in control panels, heating systems or motor starters. Installers who require a mechanical contactor with visible contact separation or a different voltage and current rating should select another device.

304 model identifier

The 304 model identifier defines the specific electrical ratings and pin configuration for this relay. Verifying that this identifier matches the specification on your schematic or existing hardware is the single step that confirms correct fitment.

Questions about this item

What does the 304 rating mean when the relay is installed in a circuit?

The 304 marking identifies this specific Hanyoung Nux solid-state relay model for ordering and replacement purposes.

Which interface standard does the HSR-3D304Z use and what does it limit in practice?

This solid-state relay switches loads through its screw-terminal power connections and a low-voltage control input; no fieldbus or communication protocol is built in.

What physical space and mounting does the HSR-3D304Z need to fit in a panel?

The unit mounts on a standard DIN rail or via its integral screw holes, requiring only the panel cut-out and clearance specified in the manufacturer's dimension drawing.
