SIEMENS GF321NR Safety Switch 30A UL with Neutral

General duty switches feature a time-proven design like Vacu-Break, SIEMENS VBII double-break switching action breaks the arc in two places. This reduces heat generation and increases switching speed by doubling the breaking distance. The result is enhanced performance and increased longevity. All GF321NR VB II safety switches have been tested not only to meet but to exceed all UL requirements. Defeatable cover interlocks on 100A - 600A to prevent the switch door from being opened when in the ON position. NEMA 3R enclosures are intended for outdoor use primarily to provide a degree of protection against falling rain and sleet, and must remain undamaged by the formation of ice on the enclosure. They are not intended to provide protection against conditions such as dust, internal condensation or internal icing.
