OS Fusible Disconnects

ABB OS Fusible Disconnects are manually operated switch fuses from 20A to 1250A. ABB OS Fusible Disconnects are available for DIN, BS, NFC, CC, JJ, and L types. The ABB OS is reliable in extreme conditions, enabling rapid fault clearance and maintaining protection levels even after a fault occurs. These disconnects are easy to install and feature interlocking fuse covers that prevent opening while the switch is in the ON position. The fuse links are fully isolated from both ends when the switch is in the OFF position.
