Why Choose the ABB E91HN20 Fuse Holder?
The ABB E91HN20, also designated E 91HN/20, is a compact 1P+N modular fuse holder designed for low-voltage circuit protection using 8.5 × 31.5 mm cylindrical fuse links. Rated at 20 A, it provides a practical fuse-based protection and isolation solution for electrical distribution and control installations.
As part of ABB's modular fuse protection range, the E91HN20 combines a protected phase pole with a neutral pole in a compact format suitable for DIN rail installations. Its replaceable cylindrical fuse arrangement enables straightforward circuit protection while allowing convenient inspection and replacement of the fuse link when required.
With a 20 A rated current and compatibility with 8.5 × 31.5 mm cylindrical fuses, the E91HN20 is suited to auxiliary, control and distribution circuits where compact fuse protection is required. ABB order code 2CSM200963R1801 identifies this specific 1P+N version.

Reliable Fuse Protection for Low-Voltage Circuits
Cylindrical fuse holders provide a straightforward means of incorporating replaceable overcurrent protection into electrical distribution systems. When fitted with a correctly selected fuse link, excessive current causes the fuse element to operate and interrupt the protected circuit, helping protect conductors and connected equipment.
The ABB E91HN20 combines this established protection method with a compact 1P+N configuration and compatibility with 8.5 × 31.5 mm cylindrical fuse links. Its modular construction makes it suitable for organised distribution boards and industrial control-panel assemblies.
Typical Applications
- Low-voltage electrical distribution boards.
- Industrial control panels and switchboards.
- Machine and automation circuits.
- Commercial electrical installations.
- Auxiliary and control circuit protection.
- Circuits requiring compact cylindrical fuse protection.
