Why Choose the ABB OHB145J12T Operating Handle?

The ABB OHB145J12T, order code 1SCA022652R2570, is a genuine ABB black pistol-type operating handle with TEST-OFF-ON / TEST-O-I indication designed for compatible ABB low-voltage switching equipment. As part of the ABB 311031-OS/OESA Accessories product group, it provides a robust external operating interface for professional switchgear and electrical distribution installations.

The OHB145J12T features a 145 mm handle length and is designed for use with a 12 mm diameter operating shaft. Its TEST switching indication allows the associated compatible switch mechanism to provide clearly identified TEST, OFF and ON operating positions, making it particularly useful where a dedicated test position is required.

Designed for demanding industrial environments, the OHB145J12T provides IP65 protection and is associated with NEMA Type 1, 3R and 12 enclosure applications. The handle is padlockable with up to three padlocks in the OFF position and provides door interlocking in the ON position, supporting secure operation of enclosed electrical switching equipment.

TEST-OFF-ON Control for ABB Switchgear

External operating handles allow compatible switching equipment installed inside an electrical enclosure to be controlled from the enclosure door. The ABB OHB145J12T combines robust manual operation with dedicated TEST-OFF-ON / TEST-O-I indication, providing clear identification of the available operating positions when used with a compatible switching mechanism.

The handle's IP65 construction supports demanding industrial enclosure applications, while padlocking in the OFF position provides a means of securing the associated switch against unintended operation. Door interlocking in the ON position helps restrict enclosure access while the switch is operating, with the interlocking arrangement capable of being defeated where permitted for authorised inspection.

Typical Applications

  • Compatible ABB switch-disconnector installations.
  • ABB switch-fuse operating mechanisms.
  • Industrial electrical switchboards.
  • Low-voltage power distribution panels.
  • Applications requiring TEST-OFF-ON switch indication.
