Solid State Relay for Electricians

The Hanyoung Nux HSR-3D404Z is a solid state relay built for electrical control tasks. It arrives new in a single pack with a red finish and is sold by the box. The unit carries a three-year parts and one-year labor coverage period.

Fits Standard Control Panels

This relay mounts into typical DIN rail or panel layouts used in automation cabinets. Its solid state design removes moving contacts, freeing up maintenance time otherwise spent on contact wear or coil replacement. The compact form factor leaves room for adjacent modules in dense enclosures.

Upgrade from Electromechanical Relays

The switch to solid state suits circuits that cycle frequently or sit in vibration-heavy environments. It is not for installers who need dry-contact isolation for very low-level signal switching or who require multiple pole configurations in a single housing. The jump pays off when silent, bounce-free operation is the priority.

Questions about this item

What is the main thermal limit when the relay runs continuously at its 404 A rating?

The solid-state switch generates heat proportional to load current; without an adequately sized heatsink the junction temperature will exceed its safe limit and the device will shut down or degrade.

How much acoustic noise and heat does the unit produce during all-day operation?

There are no moving parts, so the relay itself is silent; all heat comes from the power semiconductors and must be removed by the external heatsink you provide.

What external components must I already have to install and operate this relay?

You need a suitable heatsink, thermal interface material, a DC control signal within the specified input range, and correctly rated wiring and over-current protection for the load circuit.
