ABB OS100GJ03 – Frequently Asked Questions
1) Does the ABB OS100GJ03 switch fuse come with a handle and shaft?
No. The OS100GJ03 ships as the switch body only, with handle and shaft not included. You order the operating handle and shaft separately to match the enclosure depth and mounting you are building into. Budget for that hardware before you schedule the install, or the disconnect cannot be operated once it is mounted.
2) What size and class of fuse does the ABB OS100GJ03 take?
It is built for Class J fuses only, sized to 100A at 600V. Class J bodies are physically smaller than Class H or R of the same amperage and use their own rejection dimensions, so an RK5 or a Class H one-time fuse will not seat in it. Order 100A, 600V Class J links.
3) Can I use this ABB 100A Class J switch fuse on a 480V three-phase feeder?
Yes. The unit is rated 600V and is a 3-pole device, so it covers the three ungrounded conductors of a 480V three-phase feeder within its 100A rating. It also suits 208V and 240V three-phase work, since 600V is the ceiling, not a requirement.
4) What does the 03 (left side) designation on the ABB OS100GJ03 mean for mounting?
The 03 suffix identifies a left side, front operated configuration. That fixes which side of the switch body the operating shaft and mechanism land on, so it has to agree with the way your enclosure door and handle are laid out. If your panel is built for a right hand mechanism, this is the wrong variant to order.
5) Is this ABB switch fuse a complete disconnect I can hang on a wall?
No, and that is the main thing to get straight. The OS100GJ03 is a switch fuse mechanism intended to be built into a panel or enclosure by a panel builder, not a ready-to-mount enclosed safety switch. You supply the enclosure, the handle, and the shaft. If you want something that bolts to a wall and is finished, you want a factory enclosed fused disconnect instead.
6) How many ABB OS100GJ03 units come in a pack?
Each order unit is one switch fuse, packaged 1 ea. For a three-phase job you need one unit per disconnect point, not three, since the device is already a 3-pole switch covering all three phases.
7) Where can I get the full ABB spec sheet for the OS100GJ03 switch fuse?
ABB publishes a PDF spec sheet for the OS series switch fuse, and it is the place to confirm cubicle dimensions, terminal capacity, and the matching handle and shaft part numbers before you lay out the enclosure. That document is linked on the product record alongside the 100A, 600V ratings.
