6 Causes of Solid State Relays Failures and Solutions
Mon, Oct 6, 2025
Solid-state relays (SSR) utilize semiconductor devices for switching control, eliminating mechanical wear and contact oxidation issues inherent in electromechanical relays. However, in practical applications, latent factors such as heat accumulation, long-term aging, and environmental wear can still cause SSR performance degradation or sudden failures, compromising circuit system stability. This blog dissects the 6 most common causes of SSR failures and provides corresponding solutions based on proper installation and maintenance practices. It offers clear guidance for practitioners to mitigate risks and extend equipment lifespan.
