Why Choose the ABB OSZX4 4-Pole Blown Fuse Indicator?
The ABB OSZX4 is a dedicated 4-pole blown fuse indicator for ABB OS/OSM250D–800D switch fuse equipment with a fused neutral. Supplied under ABB order code 1SCA101225R1001, it forms part of the ABB OS/OESA accessories range and provides fuse-status indication for compatible four-pole switch fuse assemblies.
Designed for use with striker-type fuses, the OSZX4 incorporates auxiliary contacts for signalling fuse status. For compatible 4-pole OS/OSM250D–800D equipment, ABB specifies 4NO + 4NC auxiliary contacts, allowing the fuse condition to be represented through auxiliary contact states for monitoring or control purposes.
The OSZX4 provides a manufacturer-matched solution for industrial switchboards and power distribution systems where rapid identification or signalling of an operated fuse is required. ABB specifies a unit weight of approximately 0.20 kg for this accessory.

Fuse-Status Signalling for 4-Pole ABB OS/OSM Assemblies
A blown fuse indicator enables an operated fuse to produce a corresponding indication rather than relying solely on manual inspection. With the OSZX4, compatible striker-type fuses actuate the indication mechanism, while the included auxiliary contacts provide electrical contact states that can be used for fuse-status monitoring within the installation.
The ABB OSZX4 is specifically configured for 4-pole OS/OSM250D–800D switches with fused neutral. Its 4NO + 4NC auxiliary contact arrangement corresponds with the four-pole configuration, making the accessory suitable for professional switchgear systems where fuse-condition signalling forms part of the monitoring or maintenance strategy.
Typical Applications
- ABB OS/OSM250D–800D switch fuse assemblies.
- 4-pole switch fuse installations with fused neutral.
- Industrial electrical switchboards.
- Low-voltage power distribution panels.
- Fuse-status monitoring circuits.
- Industrial machinery electrical systems.
- Switchgear maintenance and fault indication systems.
