Why Choose the ABB E9120S Fuseholder?
The ABB E9120S, type E 91/20S, is a compact single-pole DIN-rail fuseholder with blown-fuse indication, designed for cylindrical 8.5 × 31.5 mm fuse links. Part of ABB's E 90 range, it provides a practical solution for incorporating replaceable fuse protection into low-voltage distribution boards, switchboards and industrial control panels.
Rated at 20 A, the E 91/20S combines fuse-link accommodation with a compact modular format. The S version incorporates a blown-fuse indicator, allowing maintenance personnel to identify an operated fuse more quickly during inspection and fault finding.
The E 91/20S mounts directly onto standard DIN rail and occupies a single modular position, making it well suited to installations where panel space is limited. Its modular construction allows it to be installed alongside other ABB protection and control devices for organised and serviceable electrical assemblies.

Reliable Fuse Protection with Clear Fault Indication
Cylindrical fuseholders provide a secure connection point for replaceable fuse links, allowing a correctly selected fuse to interrupt excessive current before cables and connected equipment suffer damage. The ABB E 91/20S accommodates a single 8.5 × 31.5 mm fuse link for protection of an individual conductor or circuit.
The integrated blown-fuse indication distinguishes the E 91/20S from the standard non-indicating version. By providing a visible indication when the installed fuse has operated, it can reduce troubleshooting time and make routine maintenance more efficient in electrical panels containing multiple fused circuits.
Typical Applications
- Electrical distribution boards.
- Industrial control panels and switchboards.
- Machinery and automation circuits.
- Auxiliary and control-circuit protection.
- Commercial and industrial electrical installations.
- Circuits requiring visible blown-fuse indication.
- DIN-rail modular protection assemblies.
