Celduc Relais, a pioneering company in the domain of solid-state power switching and control, is delighted to announce the launch of its latest range of Solid State Relays (SSRs) featuring cutting-edge push-in spring terminals. As a global leader with a robust manufacturing base in France, Celduc Relais continues to set benchmarks in the industry with its innovative solutions designed to enhance efficiency and reliability in various applications.
Revolutionary design for compact and efficient installations
The newly introduced SSRs are ingeniously designed to facilitate intuitive, tool-free connections, making them ideal for compact installations where space is at a premium and time is of the essence. This groundbreaking technology ensures fast and secure wiring without the need for specialized tools, thereby significantly reducing installation times and enhancing overall productivity.
Advantages of Push-In Connections

Celduc Relais's push-in technology offers a plethora of benefits, including:
- Strength and Reliability: The connections are robust, ensuring a secure and dependable electrical contact.
- Flexibility: Suitable for a wide range of conductors including solid, stranded, and fine-stranded with crimped-on ferrules
. - Safety and Durability: Eliminates the risk of heat generation and terminal breakage inside the product. Vibrations and the need for retightening screws are no longer concerns, making these relays perfect for dynamic environments. Furthermore, the touchproof protection enhances safety by negating the need for an additional cover.
- Speed: Offers quick and effortless conductor connections through direct plug-in technology, significantly reducing downtime for relay replacement or maintenance.

Extensive Range Catering to Diverse Needs
Celduc Relais's new series spans across single phase, two-phase, three-phase, and four-legs SSRs, each designed to cater to specific requirements and applications. The series includes models such as SOR, SOBR, SGTR, and SMQR, with various configurations to support different power and control wiring needs.
Features Across the Range
- Models suitable for resistive loads and various types of loads, ensuring versatility across applications.
- Integrated protections such as TVS (Transient Voltage Suppressor) diodes and voltage protection on inputs to safeguard against overvoltages.
- "Ready to use" models with integrated heatsinks for enhanced thermal management and operational efficiency.
- Green control status LEDs for at-a-glance monitoring of relay operation.
Celduc Relais's commitment to innovation is further demonstrated in the detailed engineering of these SSRs, where each model is designed to ensure optimal performance even in tight spaces, highlighting the company's dedication to meeting the evolving needs of the industry.
