Why Choose the ABB 2CSM200923R1801 E 91/32 Fuse Switch Disconnector?
The ABB 2CSM200923R1801, also identified as the ABB E 91/32, is a compact single-pole fuse switch disconnector designed to provide dependable overcurrent and short-circuit protection in low-voltage electrical installations. It accommodates a replaceable cylindrical fuse link, enabling circuits to be protected and safely isolated for inspection, maintenance or fuse replacement.
As part of the established ABB E 90 range, this modular fuse holder is suitable for residential, commercial and industrial distribution systems. Its DIN rail mounting format allows straightforward integration into consumer units, distribution boards, control panels and other modular electrical enclosures.
With a rated operational current of 32 A and compatibility with 10 × 38 mm cylindrical fuse links, the ABB E 91/32 provides a practical solution for protecting individual circuits and electrical equipment. The unit does not include a blown-fuse indicator, making it suitable for installations where visual fuse-status indication is not required.

Reliable Fuse Protection and Circuit Isolation
Fuse switch disconnectors combine the protective performance of a replaceable fuse link with a convenient method of isolating a circuit. When an appropriately rated fuse is installed, excessive current causes the fuse element to operate, interrupting the circuit before cables or connected equipment sustain significant damage.
The ABB E 91/32 also enables the protected circuit to be disconnected during servicing. Its modular construction, durable thermoplastic housing and DIN rail compatibility make it suitable for professional electrical installations where reliable protection and efficient panel assembly are required.
Typical Applications
- Residential and commercial distribution boards.
- Industrial control panels.
- Machinery and equipment protection.
- Lighting and auxiliary circuits.
- Heating and ventilation systems.
- Building automation installations.
