Why Choose the ABB E9132S Fuseholder?
The ABB E9132S, type E 91/32S, is a compact single-pole DIN-rail fuse switch disconnector with blown-fuse indication, designed for cylindrical 10.3 × 38 mm fuse links. Part of ABB's E 90 range, it provides overcurrent and short-circuit protection when fitted with a correctly selected fuse link and is suited to low-voltage distribution boards, switchboards and industrial control panels.
Rated at 32 A, the E 91/32S supports operational voltages up to 690 V AC in AC-20B applications and 400 V AC in AC-22B applications. Its rated insulation voltage is 1 kV, while the compact single-module construction allows effective use of available DIN-rail space.
The S version incorporates an LED blown-fuse indicator, making it easier to identify an operated fuse during inspection and fault finding. The indicator operates across a wide 24–1000 V AC/DC auxiliary voltage range, providing a practical visual maintenance aid in electrical installations.

Reliable Fuse Protection with Visual Fault Indication
The ABB E 91/32S provides a secure connection and switching point for a cylindrical fuse link, allowing a correctly selected fuse to protect the downstream circuit against overcurrent and short-circuit conditions. Its 32 A rating and 10.3 × 38 mm fuse format make it suitable for a broad range of modular low-voltage protection applications.
The integrated LED blown-fuse indicator provides a clear visual maintenance aid when the installed fuse operates. Combined with its compact DIN-rail construction and single-module width, this makes the E 91/32S particularly useful in panels containing multiple fused circuits where fast fault identification and efficient use of installation space are important.
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.
