Why Choose the ABB E91N125 Fuseholder?
The ABB E91N125, type E 91N/125, is a heavy-duty 1P+N cylindrical fuseholder designed for industrial circuit protection using 22 × 58 mm fuse links. Part of the ABB E 90/125 series, it provides a compact DIN-rail solution for incorporating high-current cylindrical fuses into distribution boards, control panels and industrial electrical installations.
The E91N125 provides one protected phase pole plus a concurrently switched neutral, allowing both conductors to be disconnected together while the fuse provides protection in the phase conductor. Its holder is designed for cylindrical fuse links in the ABB E 90 50/125 range and supports applications requiring currents up to 125 A.
Rated for operation up to 690 V AC, the E91N125 combines DIN-rail mounting, an IP20 degree of protection and a padlockable mechanism for safer maintenance isolation. Its four-module construction and robust terminals make it suitable for demanding industrial power-distribution and machinery applications.

Reliable High-Current Fuse Protection for Industrial Circuits
The ABB E 90/125 range is designed to accommodate 22 × 58 mm cylindrical fuse links for industrial circuit protection. By combining the fuseholder with a correctly selected fuse link, the E91N125 provides a practical means of integrating overload and short-circuit protection into electrical distribution and machinery circuits.
The 1P+N arrangement is particularly useful where simultaneous phase and neutral disconnection is required. For maintenance, the holder can be padlocked in its open position, helping prevent unintended reconnection while work is being carried out on downstream equipment.
Typical Applications
- Industrial electrical distribution boards.
- Machinery and automation control panels.
- High-current branch circuit protection.
- Commercial and industrial switchboards.
- OEM machinery and electrical assemblies.
- Circuits requiring simultaneous phase and neutral isolation.
