Why Choose the ABB E91N125S E 91N/125s Fuseholder?
The ABB E91N125S (E 91N/125s) is a robust 1P+N modular fuseholder / fuse disconnector designed for cylindrical 22 × 58 mm fuse links in industrial and commercial electrical distribution systems. As part of the proven ABB E 90 / System pro M compact range, it provides dependable fuse protection and circuit isolation in a compact DIN-rail format.
Designed for protection against overloads and short circuits when fitted with a suitable fuse link, the E 91N/125s combines a switched phase pole with a simultaneously switched neutral. The “s” version incorporates a blown-fuse indicator, providing convenient visual indication of fuse operation and helping maintenance personnel identify an operated fuse more quickly.
With its 1P+N configuration, compatibility with 22 × 58 mm cylindrical fuses and rated operational voltage up to 690 V AC/DC, the E 91N/125s is well suited to distribution boards, machinery, control panels and industrial installations. Its four-module construction allows straightforward mounting on standard DIN rail alongside other ABB System pro M compact protection devices.

Reliable Fuse Protection and Phase-Neutral Isolation
Cylindrical fuseholders provide a simple and dependable means of integrating fuse protection into low-voltage electrical systems. When a correctly selected fuse link is installed, excessive current caused by an overload or short circuit causes the fuse element to operate, disconnecting the protected circuit and helping safeguard downstream wiring and equipment.
The ABB E 90 range combines modular DIN-rail installation with accessible fuse replacement and circuit isolation. The E 91N/125s adds simultaneous neutral switching and blown-fuse indication, making it particularly useful where both phase and neutral isolation are required and rapid identification of an operated fuse can simplify inspection and maintenance.
Typical Applications
- Industrial electrical distribution boards.
- Commercial low-voltage distribution systems.
- Machinery and automation control panels.
- Phase and neutral circuit isolation.
- Power supply and feeder circuit protection.
- Industrial equipment and production machinery.
- OEM switchboards and electrical control assemblies.
