Why Choose the ABB E91HN20S Fuse Holder?
The ABB E91HN20S, also designated E 91HN/20S, is a compact 1P+N modular fuse holder designed for protection and isolation of electrical circuits using 8.5 × 31.5 mm cylindrical fuse links. With a rated current of 20 A, it provides a practical fuse-based protection solution for compatible low-voltage distribution and control applications.
As part of ABB's modular fuse protection range, the E91HN20S combines the phase fuse holder with a switched neutral pole in a compact DIN rail format. This configuration allows simultaneous phase and neutral disconnection while the fuse link provides overcurrent protection on the protected phase conductor.
Designed for professional electrical installations, the E91HN20S supports straightforward fuse inspection and replacement while integrating neatly alongside other modular protection and control devices. ABB order code 2CSM200703R1801 identifies this specific 20 A, 1P+N version.

Reliable Fuse Protection for Low-Voltage Circuits
Cylindrical fuse holders provide a convenient means of incorporating replaceable overcurrent protection into electrical distribution systems. When an appropriate fuse link is fitted, excessive current causes the fuse element to operate and interrupt the protected circuit, helping protect wiring and connected equipment against damaging overcurrent conditions.
The ABB E91HN20S combines this fuse-protection function with a 1P+N configuration, allowing the phase and neutral conductors to be disconnected together. Its modular DIN rail construction makes it well suited to organised distribution boards and industrial control-panel assemblies.
Typical Applications
- Low-voltage electrical distribution boards.
- Industrial control panels and switchboards.
- Machine and automation control circuits.
- Commercial electrical installations.
- Auxiliary and control circuit protection.
- Circuits requiring cylindrical fuse protection and neutral switching.
