Why Choose the ABB OS32FBS40A1N1 Side-Operated Switch Fuse?

The ABB OS32FBS40A1N1 is a compact 32 A 4-pole side-operated switch fuse from the ABB OS Mini range, designed for reliable switching, isolation and fuse protection in industrial low-voltage systems. Identified by ABB order code 1SCA109006R1001, it is designed for A1 British Standard fuse links.

This configuration incorporates three fused phase poles and an N1 non-fused switched neutral on the left side. Side operation makes the device suitable for switchboard and enclosure layouts where lateral actuation is preferred, while the switched neutral enables coordinated isolation of three-phase circuits with neutral.

The OS32FBS40A1N1 is rated for AC-20 to AC-23 operation up to 690 V AC and provides AC-23 operational power ratings of 15 kW at 415 V, 18.5 kW at 500 V and 22 kW at 690 V. It features protected tunnel terminals and is supplied with a black ON-OFF handle and adjustable shaft as standard.

Key Advantages

  • 32 A rated current in a compact OS Mini format.
  • 4-pole arrangement for three-phase circuits with neutral.
  • N1 non-fused switched neutral positioned on the left side.
  • Side-operated design for flexible switchboard integration.
  • Designed for A1 British Standard fuse links.
  • Supplied with black ON-OFF handle and adjustable shaft.

Key Features

  • ABB OS Mini switch fuse.
  • 32 A rated operational current.
  • 4-pole configuration.
  • Three fused phase poles plus N1 non-fused switched neutral.
  • Side-operated construction.
  • A1 fuse size.
  • AC-20 to AC-23 operation up to 690 V AC.
  • Protected tunnel terminals with IP20 protection.
  • Black ON-OFF handle is IP65 protected and padlockable in the OFF position.
  • Adjustable operating shaft supports different installation depths.

Compact Side-Operated Fused Isolation

Switch fuses combine manual circuit switching and isolation with fuse-based protection against overcurrent and short-circuit conditions. The OS32FBS40A1N1 provides fuse protection on the three phase conductors while its N1 pole switches the neutral through a non-fused connection, enabling coordinated disconnection of the supply.

Its compact OS Mini construction, side-operated mechanism, A1 fuse compatibility and supplied handle and shaft make the ABB OS32FBS40A1N1 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.
