Schneider Electric Introduces Heavy-Duty Solar Disconnect Switch

Schneider Electric has launched the Square D 1000 VDC disconnect switch, which the company says is the first enclosed heavy-duty 1000 VDC solar disconnect on the market. The switch functions as a local disconnect for a string of photovoltaic panels and is designed for an extended life expectancy in harsh environments.

Suitable for both grounded and ungrounded PV systems, the Square D 1000 VDC disconnect switch offers a preconfigured solar solution and familiar enclosed safety switch design, with no additional components required, the company says. The 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, Schneider Electric adds. The unit operates within a temperature range of -37 degrees C to 50 degrees C, using a white enclosure that can reduce solar gain by up to 35% over standard gray enclosures.
