Disconnect switch

Disconnect switchSchneider Electric has launched the Square D 1000 VDC disconnect switch, the first enclosed heavy-duty 1000 VDC solar disconnect on the market. The easy-to install switch functions as a local disconnect for a string of PV panels and is designed for an extended life expectancy in harsh environments. Suitable for grounded and ungrounded PV systems, the Square D 1000 VDC disconnect switch offers a pre-configured solar solution and familiar enclosed safety switch design, with no additional components required. The extended life expectancy exceeds IEC 60947-3 mechanical endurance requirements by a factor of 18, and IEC 60947-1 electrical endurance requirements by a factor of 10. The NEMA Type 3 and IP63 enclosure is resistant to windblown dirt and dust and exceeds NEMA type 3R. It operates within a temperature range of -37° C to 50° C, using a white enclosure that can reduce solar gain by up to 35% over standard grey enclosures. The Square D 1000 VDC disconnect switch is available now through regular Schneider Electric distribution channels.
