This switch disconnector provides manual isolation of two-pole circuits rated up to 1500VDC at 160A, allowing safe disconnection of power supply during maintenance or emergency shutdown. The size 1 frame suits control panel power distribution applications where DC isolation is required. It is typically installed as part of the main disconnect arrangement ahead of downstream protective and control devices.
