Abb Switch Disconnector 16A 2 Pole 660 Vdc OTDC16F2

The OTDC range of switch disconnectors is specially designed for DC applications. Thanks to the compact design, efficiency and reliability of the OTDC range, PV systems reach a new level of development. The versatile OTDC range includes solutions for systems with the most stringent requirements: voltage class of 1500 VDC, multi-circuit disconnection, and combined load outputs up to 1500 A.
