Mersen USBB3PH25K6 – Frequently Asked Questions

1) How many fuse holders does the USBB3PH25K6 bus bar feed, and is it single or three phase?
Model USBB3PH25K6 is a 6-pole, 3-phase bar, so it ties six fuse holder poles into three phases (two poles per phase). Mersen also builds the USBB in 1-phase and 2-phase configurations if your circuit combination is different.
2) Is this bus bar rated for a 480V or 600V industrial control panel?
Yes. The USBB UltraSafe bus bar carries a 600V AC UL rating, so a 480V or 600V AC control panel is within rating. For DC applications such as solar or battery circuits it is rated 1000V DC UL.
3) Is the Mersen USBB bus bar touch safe with the panel door open?
The USBB is a touch-safe, shock-resistant design, with the conductor shrouded so fingers cannot reach live metal during service. That is the main reason panel builders choose it over bare copper bar or exposed jumper wiring where technicians work in an energized enclosure.
4) Why use a bus bar instead of just wiring the fuse holders together?
Two reasons drive it. Wiring six poles individually means cutting, stripping and terminating a dozen jumpers; the USBB drops on and lands the whole phase group at once, cutting install labor. It also takes less room than a wire bundle, which matters in compact panels where gutter space is already tight. The trade-off is that the bar commits you to UltraSafe USCC or USM holders in adjacent positions, so if your fuse holders are scattered across a DIN rail, wire is still the answer.
5) Is the Mersen USBB sold individually or in a box?
It is supplied 50 each per package, which suits production panel-building operations rather than a one-off repair. Plan the order quantity around that pack size.
6) Is the Mersen USBB bus bar RoHS compliant for export panel builds?
Yes, the USBB UltraSafe bus bar system is RoHS compliant, which covers restricted-substance requirements on panels being shipped into markets that demand it.
