Why Choose the ABB E91N50S E 91N/50s Fuseholder?
The ABB E91N50S (E 91N/50s) is a robust 1P+N cylindrical fuseholder with blown-fuse indication, designed to protect electrical circuits against overloads and short circuits when fitted with a correctly selected fuse link. Part of the ABB E 90 50/125 range, it accepts 14 × 51 mm cylindrical fuses and has a rated current of 50 A.
The E 91N/50s combines one protected phase pole with a switched neutral in a compact DIN-rail device. Its rated operational voltage is up to 690 V AC, while the integrated blown-fuse indicator provides convenient visual identification when the installed fuse has operated.
Designed for professional distribution and control applications, the E 91N/50s occupies 3 DIN modules and provides a practical combination of fuse protection, switching and fault indication. Its modular format makes it suitable for industrial, commercial and infrastructure electrical panels where replaceable cylindrical fuse protection is required.

Reliable Fuse Protection with Visual Fault Indication
Cylindrical fuseholders provide a straightforward method of incorporating replaceable overcurrent protection into modular electrical distribution systems. When the ABB E 91N/50s is fitted with a correctly rated 14 × 51 mm cylindrical fuse, the fuse provides protection against overload and short-circuit currents while the fuseholder provides the mechanical interface and switching arrangement.
The 1P+N configuration combines phase protection with neutral switching, while the integrated blown-fuse indicator makes it easier to identify an operated fuse during inspection and troubleshooting. Its 3-module DIN-rail construction provides a compact solution for higher-current distribution and control circuits.
Typical Applications
- Industrial electrical distribution panels.
- Commercial distribution boards.
- Control and automation cabinets.
- Single-phase circuits requiring neutral switching.
- Overload and short-circuit protection.
- Circuits requiring visible blown-fuse indication.
- DIN-rail fuse protection assemblies using 14 × 51 mm cylindrical fuses.
