surge protective devices (SPDs) for electrical systems, understanding Maximum Continuous Operating Voltage (MCOV) is critical for ensuring reliable, long-term protection. The MCOV SPD rating determines whether your surge protection device can withstand the continuous voltage stresses present in your electrical system without premature failure. This comprehensive guide explores everything electrical engineers, facility managers, and procurement specialists need to know about MCOV for SPD applications, from fundamental concepts to practical selection criteria. Selecting an SPD with the incorrect MCOV rating can lead to nuisance tripping, equipment damage, or complete protection system failure.
