Disconnect switches

OT Non-fusible disconnects

Disconnect switches are typically used in isolating individual strings of PV arrays and
battery banks or as the main switch for the PV system, AC and DC. ABB’s solar
switches are compact, have exceptional DC voltage ratings and are available in both
open and enclosed configurations.

This offering includes DC rated switches 16-630 A IEC and 28-400 A UL. For the AC
side of solar circuits, ABB’s standard UL fusible and non-fusible OS/OT disconnects
provide a perfect solution.
