German solid-state relay contactor

The 3RF3405-1BB04 is a solid-state relay contactor designed for switching AC loads in industrial control cabinets and automation panels. It suits engineers and integrators who need silent, bounce-free switching without mechanical wear. Buyers requiring DC load switching or higher current ratings than the specified 4 A will need a different device.

Sustained-load behaviour

Solid-state construction eliminates contact erosion, so the relay maintains consistent switching characteristics over millions of cycles under continuous operation. Thermal management is handled through the integral baseplate, allowing stable performance during extended duty cycles. The zero-cross turn-on feature reduces inrush stress on connected loads, contributing to long-term reliability in repetitive switching applications.

Questions about this item

Does the 3RF3405-1BB04 solid state relay contactor generate noticeable heat or noise when running continuously?

As a solid state relay, the 3RF3405-1BB04 has no moving parts, so it operates silently and produces minimal heat compared to mechanical contactors under normal load.

What voltage or control signal must my system already provide to activate the 3RF3405-1BB04 relay?

The 3RF3405-1BB04 requires a compatible control voltage input, typically in the low-voltage DC range, to switch the main power circuit; verify your controller matches the relay's specified input rating before installation.
