Why Choose the ABB E9150S E 91/50s Fuseholder?
The ABB E9150S (E 91/50s) is a single-pole 50 A DIN-rail fuseholder designed for cylindrical 14 × 51 mm fuse links. Part of ABB’s E 90 50/125 range, it provides a compact solution for protecting industrial electrical circuits against overload and short-circuit conditions when fitted with a correctly selected fuse.
Rated for 50 A and up to 690 V AC/DC, the E 91/50s combines fuse protection with convenient isolation of the fuse link from the circuit. Its single-pole configuration occupies only 1.5 DIN modules, making it suitable for distribution boards, switchgear and control panels where installation space is valuable.
The “s” version incorporates a blown-fuse indicator, providing a visual indication when the installed fuse has operated. This can simplify fault identification and maintenance, particularly in industrial installations where rapid recognition of a blown fuse helps reduce troubleshooting time.
Key Advantages
- 50 A rated current for industrial circuit-protection applications.
- Designed for standard 14 × 51 mm cylindrical fuse links.
- Single-pole configuration for individual conductor protection.

Cylindrical Fuse Protection for Industrial Circuits
Cylindrical fuseholders provide a secure interface between an electrical circuit and a replaceable fuse link. When a correctly selected fuse is installed, the combination provides protection against overload and short-circuit conditions while allowing the fuse to be accessed and replaced without changing the complete protective device.
The ABB E 91/50s is designed specifically around the widely used 14 × 51 mm cylindrical fuse format. Its 50 A rating, high operational-voltage capability and integrated blown-fuse indication make it particularly useful in industrial distribution, machinery and control-panel applications where reliable protection and straightforward fault identification are required.
Typical Applications
- Industrial electrical distribution boards.
- Machinery and equipment protection.
- Control and automation panels.
- Motor-related auxiliary circuits.
- Heating and control circuits.
- Commercial electrical distribution.
- Switchgear and panel assemblies.
- Circuits requiring 14 × 51 mm cylindrical fuse protection up to 50 A.
