SF5 : miniature relay which saves place in your control panels

The SF548340 from celduc® relais is a very small power solid state relay (SSR) designed to deliver high switching performance in a compact footprint. Combining robustness, reliability, and compliance with international standards, it is an ideal solution for modern industrial and automation applications where space, efficiency, and safety are critical.

Compact Design, powerful performance and fast FASTON connection

Despite its miniature size, the SF548340 is capable of switching loads up to 30 A at 230 VAC, making it a top choice for applications requiring high electrical performance while having very limited space available. The device includes a visual LED on its input, providing a clear indication of the presence of the control signal and confirming that the relay is activated.

Equipped with FASTON terminal connections, the SF548340 enables fast, reliable and easy-to-implement wiring, thereby facilitating installation and maintenance in the field.

Its compact format allows designers to optimize space in control cabinets, machines and distributed systems, without compromising electrical performance.

Compliance and safety you can trust

The SF548340 is designed in accordance with major international standards, ensuring safe integration worldwide:

• CE and UKCA
