Designed for PV applications, 1,000 Vdc OTDC switches come in 250, 320, and 400 A versions that achieve 1,000 Vdc rating per UL 98B. Dual magnetic breaking design breaks circuit in 2 places, increasing air gap while reducing time to circuit isolation. Permanent magnets pull arc into arc chutes for accelerated extinguishing. Along with integrated heat sink, features include visible contacts that promote safety and reliable quick-make, quick-break operation.
