HR17 Series lsolating Switches and Fuse-Type lsolating Switches

Product Overview

The HR17 series fuse-type isolating switches are capable of on-load operation and are suitable for rated currents ranging from 40 A to 630 A They feature top and bottom input/output configurations, with blade. type terminals and arc-extinguishing devices; the switch housing is fitted with sealed inspection ports at regular intervals, and incorporates built-in signal switches and test switches. A fuse monitor is available as an option, and the switches can also be used as knife switches
The switches feature an attractive, innovative and streamlined design,
and comply with the lEC 60947-3 and GB/T 14048.3 standards.
