Why Choose the ABB OS32FBS40A2N1 Side-Operated Switch Fuse?
The ABB OS32FBS40A2N1 is a compact 32 A 4-pole side-operated switch fuse from the ABB OS Mini range, designed for dependable switching, isolation and fuse protection in industrial low-voltage systems. Identified by ABB order code 1SCA109007R1001, this model is designed for A2 British Standard fuse links.
This configuration incorporates three fused phase poles and an N1 non-fused switched neutral on the left side. Its side-operated construction supports switchboard and enclosure layouts where lateral operation is preferred, while the switched neutral provides coordinated isolation for three-phase circuits with neutral.
The OS32FBS40A2N1 is rated for AC-20 to AC-23 operation up to 690 V AC, with AC-23 operational power ratings of 15 kW at 415 V, 18.5 kW at 500 V and 22 kW at 690 V. Protected IP20 tunnel terminals, an adjustable shaft and an IP65 black ON-OFF handle support practical installation in industrial equipment.

Compact Side-Operated Fused Isolation
Switch fuses combine manual switching and circuit isolation with fuse-based protection against overcurrent and short-circuit conditions. The OS32FBS40A2N1 protects the three phase conductors with A2 fuse links while its N1 pole provides non-fused switching of the neutral, allowing coordinated disconnection of a three-phase supply with neutral.
Its compact OS Mini construction, side-operated mechanism, protected tunnel terminals and supplied operating components make the ABB OS32FBS40A2N1 particularly suitable for machinery, control panels and distribution assemblies where installation space and dependable four-pole isolation are important.
Typical Applications
- Industrial control panels and distribution boards.
- Three-phase systems requiring switched neutral isolation.
- Machinery and equipment power isolation.
- Compact switchgear assemblies.
- Fused feeder and distribution circuits.
- OEM automation and process-control equipment.
