Reliable Fuse Protection with Status Indication
Cylindrical fuse disconnectors provide a practical way to integrate replaceable fuse links into industrial low-voltage circuits while also providing a means of circuit isolation. When fitted with a correctly selected 22 × 58 mm fuse link, the ABB E91125S supports overload and short-circuit protection according to the characteristics of the installed fuse.
The s version incorporates a blown-fuse indicator, allowing maintenance personnel to identify fuse operation more easily. Combined with its DIN-rail construction and padlockable open position, this makes the E91125S particularly suitable for industrial switchboards and machinery where convenient servicing and safe isolation are important.
Typical Applications
- Industrial electrical switchboards.
- Control and automation panels.
- Industrial machinery and production equipment.
- Power distribution and feeder circuits.
- Higher-current auxiliary and control circuits.
