The Siemens SIRIUS 3UG3208-1A is a sealable cover designed specifically for the 3UG308 insulation monitor. It carries a rated voltage range of 110 to 400 V, with an initial value of 0.85 and a full-scale value of 1.1, meaning it accommodates the monitor's threshold adjustment across that span. The cover mounts in any position, which simplifies panel layout when the monitor is placed in a tight or non-standard orientation.
