protect your electrical equipment. Uc represents the maximum continuous operating voltage, while Up indicates the voltage protection level that limits surge voltage during activation. Understanding these parameters correctly ensures optimal surge protection and prevents costly equipment damage. What Do Uc and Up Mean on SPD? Essential Definitions Uc: Maximum Continuous Operating Voltage Uc (Maximum Continuous Operating Voltage) is the maximum AC or DC voltage that can be continuously applied to the SPD without causing activation or degradation. This parameter determines when the SPD remains inactive during normal operating conditions.
