SEL-3355 Computer
Designed as a server-class computer, the tough SEL-3355 Computer is built to withstand harsh environments in utility substations, industrial control, and automation systems. By eliminating all moving parts, including rotating hard drives and fans, and using error-correcting code (ECC) memory technology, SEL computers have over ten times the mean time between failures (MTBF) of typical industrial computers. Designed, manufactured, and tested to the same standards as our protective relays, every SEL-3355 comes with an unprecedented ten-year, worldwide SEL warranty.
