ASCO 330yc05awrl2s Surge Protective Device SPD

ASCO 330YC05AWRL2S is a panel-mount Surge Protective Device (SPD) in ASCO’s 300 Series, engineered to protect electrical panels and control cabinets from damaging transient surges. The unit is parallel-connected, with a Maximum Continuous Operating Voltage (MCOV) of 120 VAC at 125% and 115% for other voltages, a Short-Circuit Current Rating (SCCR) of 65 kAIC, and a surge current rating of 50–80 kA per mode and 100–160 kA per phase, depending on configuration. The exact model number, 330YC05AWRL2S, is listed in ASCO’s panel-mount SPD documentation, confirming its mounting style and series placement. Its panel-mount design facilitates integration into standard electrical cabinets and control panels, allowing surge protection to be placed close to sensitive loads. When installed in a panel, this SPD diverts surge energy away from protected circuits, helping to shield sensitive components from voltage transients on typical distribution networks. Proper wiring, adherence to the installation manual, and regular maintenance are recommended to ensure continued protection and reliable operation.
