SRP1-CB and SRP1-CR Series SSRs

In industrial and commercial settings, unexpected relay failures can lead to costly downtime and safety hazards. The Littelfuse/IBU SRP1-CB and SRP1-CR solid-state relays (SSRs) address this issue with a design focused on reliability and longevity, even in the most challenging environments.

The SRP1-CB high-endurance series of multipurpose SSRs ensure superior uptime. Designed for high frequency operation, the SRP1-CB series provides consistent and reliable performance for applications that demand extensive on/off switching. The relays’ broad voltage range, zero cross, and instantaneous switching make them compatible across a wide selection of single-phase and high-power three-phase applications from industrial machinery to commercial use.

The SRP1-CR high-endurance series are multipurpose SSRs with everything needed to ensure better uptime while allowing a fast, safe, and easy installation. Overvoltage protection is ensured through the use of Littelfuse SMBJ series TVS diodes inside to safeguard the relay’s operation, even in the event of electrical spikes within the network. The IP20 plastic cover provides finger-safe protection for the user by preventing accidental contact with live terminals. A pre-attached thermal pad eliminates the need for thermal paste application, ensuring an easy and clean installation with efficient heat dissipation.
