Benefits of choosing quality over price for solid-state relays

Littelfuse has published its ‘Littelfuse Solid-State Industrial Relays Quality Test Report’. This paper addresses the risks of choosing a low-quality solid-state relay (SSR) and shares the test results of the Littelfuse products compared to three other suppliers.

Solid-state relays are a critical component in modern electrical and electronic systems providing reliable switching capabilities for various applications. But low-cost SSRs are often made by low-quality manufacturers who do not follow the strict standards and requirements needed for commercial applications. This can lead to mechanical failures under constant and prolonged use.

“When it comes to choosing the right solid-state relay for your application, it’s important to know the quality of the product you are purchasing so that it can withstand the demands of industrial and commercial settings,” said Hugo Neri, Relays Product Manager at Littelfuse.


“By choosing a quality solid-state relay, it minimises serious risks such as fire hazards, electrical shock and injury as well as costly disruptions caused by unreliability and poor performance.”

This technical paper includes:

  • Risks to using poor quality SSRs
  • How to choose a quality SSR
  • Solid-state relay endurance testing and performance evaluation
  • Testing setup and methodology
  • Test criteria
  • Endurance test results
