Mersen UL508 Disconnect Switch M403DM

Description
Mersen offers a range of DC disconnect switches especially designed for PV applications, in 2 poles and 2x2 poles configurations for double circuit applications. The technology inside the switch and the visible contacts allow a quick, safe, and reliable DC breaking power at all current levels up to 1000VDC. With a symmetric 2-pole design, the product is ready and simple to install independently of the polarity, with very limited power losses, and with a smaller footprint than competition. Features Compact Robust DIN-rail, base, or door mounting Choice of handles and shafts Padlockable Side-mount auxiliary contacts and additional poles Double-break, silver-plated, contacts Applications Line-of-sight disconnect Electrical isolation Branch-circuit switch Motor disconnect
