The tough SEL-3360 Compact Industrial Computer is built to withstand harsh environments in utility substations, industrial control systems, and automation systems. By eliminating all moving parts (including rotating hard drives and fans) and using error-correcting code (ECC) memory technology, SEL compact industrial 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-3360 comes with an unprecedented ten-year worldwide SEL warranty.
