celduc relais: SF548340 New Miniature Solid State Relay
June 9, 2026
The SF548340 from celduc relais is an ultra-compact solid state relay (SSR). It delivers high switching performance while taking up very little space.
As a result, it is an excellent choice for modern industrial and automation systems. It combines reliability, durability, and compliance with international standards. Therefore, it is ideal for applications where space, efficiency, and safety are key requirements.
Compact design with high performance
The SF548340 requires only 30% of the space typically needed by a standard hockey puck SSR.
Despite its miniature size, it can switch loads up to 30 A at 230 VAC. Therefore, it is well suited for applications that demand high electrical performance in a limited space.
In addition, the relay features an input status LED. This visual indicator clearly shows when the control signal is present and confirms that the relay is active.
Fast and easy wiring with FASTON terminals
The SF548340 is equipped with FASTON terminal connections. As a result, wiring is quick, simple, and reliable.
Moreover, installation and maintenance become easier for machine builders and maintenance teams.
Thanks to its compact footprint, the relay fits easily into control panels, industrial machines, and distributed systems. Consequently, designers can optimize available space without sacrificing performance.
Compliance and safety you can trust
The SF548340 complies with major international standards. Therefore, it can be integrated into equipment intended for global markets.
Key certifications include:
- CE and UKCA markings
- UL approval for North American markets
- VDE certification for European compliance
- RoHS compliance for environmentally responsible design
These certifications demonstrate compliance with strict safety, quality, and environmental requirements.
Easy integration and thermal management
The relay accepts a 3–32 VDC control input. As a result, it is compatible with most PLCs and standard control systems.
Furthermore, it can be easily mounted on a heatsink when required. This helps maintain optimal thermal performance, even at high current levels.
Typical applications
The SF548340 is ideal for a wide range of industrial applications, including:
- Industrial automation systems
- Heating and temperature control
- Packaging and processing machines
- Motor and resistive load control
