Why Choose the ABB OSD25P4 Blown Fuse Indicator?
The ABB OSD25P4, order code 1SCA022196R9520, is a genuine ABB 4-pole blown fuse indicator designed specifically for compatible ABB OS Mini switch-fuses. As part of the ABB 311031-OS/OESA Accessories product group, it provides mechanical blown-fuse indication for switch-fuse installations using suitable striker-type fuses.
Designed for 4-pole OS Mini switches with a fused neutral, the OSD25P4 works with the mechanical striker mechanism of the installed fuses. When a compatible striker fuse operates, the indicator provides a means of signalling the blown-fuse condition, helping maintenance personnel identify fuse operation within the switch-fuse assembly.
The OSD25P4 includes an auxiliary change-over contact (1 × C/O), allowing the fuse-status mechanism to be incorporated into compatible signalling or control arrangements. Its purpose-designed OS Mini construction provides a compact solution without requiring an electronic fuse-monitoring system.
Key Advantages

How Mechanical Blown Fuse Indication Works
Striker-type fuses incorporate a mechanical indicator that operates when the fuse element clears a fault. The ABB OSD25P4 uses this striker action to provide mechanical blown-fuse detection across a compatible 4-pole OS Mini switch-fuse arrangement. This allows fuse operation to be identified without relying on an electronic voltage-monitoring system.
The integrated 1 × C/O auxiliary contact also allows the blown-fuse mechanism to interact with compatible external signalling or control circuits. This can support applications where a fuse operation needs to be communicated to other equipment or indicated remotely as part of the installation's control scheme.
Typical Applications
- ABB OS Mini 4-pole switch-fuse installations.
- OS25–32F22 switch-fuses with compatible striker-type fuses.
- 4-pole switch-fuse arrangements with fused neutral.
- Industrial electrical distribution panels.
- Motor and machinery protection switchgear.
- Electrical control cabinets requiring blown-fuse indication.
- OEM panel building and low-voltage switchgear assemblies.

Frequently Asked Questions
What is the ABB OSD25P4 used for?
The ABB OSD25P4 is a 4-pole mechanical blown fuse indicator designed for compatible ABB OS Mini switch-fuses with a fused neutral, allowing operation of a striker-type fuse to be detected and indicated.
Which ABB switches are compatible with the OSD25P4?
The OSD25P4 is designed for 4-pole ABB OS Mini switch-fuses with fused neutral, including compatible OS25–32F22 configurations.
Does the ABB OSD25P4 require striker-type fuses?
Yes. The OSD25P4 is a mechanical blown fuse indicator and therefore requires compatible striker-type fuses for its detection mechanism to operate.
Does the ABB OSD25P4 include an auxiliary contact?
Yes. The OSD25P4 includes one change-over auxiliary contact (1 × C/O) for use with compatible signalling and control arrangements.
Is the ABB OSD25P4 an electronic fuse monitor?
No. The OSD25P4 is a mechanical blown fuse indicator that responds to the striker mechanism of compatible fuses rather than electronically monitoring the fuse voltage.
Genuine ABB Switch-Fuse Accessories
ABB blown fuse indicators provide purpose-designed fuse-status detection for compatible switch-fuse equipment, with the OSD25P4 providing 4-pole mechanical striker-fuse indication and an integrated change-over auxiliary contact for ABB OS Mini installations with fused neutral.
