LEIPOLE busbar terminals, also called mini busbars, distribute power to many connection points from one busbar inside control cabinets, switchgear and distribution boxes. Each terminal is a plated copper busbar in an insulated housing with a fixed pitch, so wiring layouts stay uniform. Earth bars / neutral bars (series B and G) provide the earth connection points. Series A to H differ by busbar cross-section, rated current, pole count and pitch, and every model has its own order number.
Key Features & Advantages
Busbar sizes from 3×17 mm to 9×19 mm, rated current up to 375 A (series A)
Pole counts from 4 to 50, with fixed lengths and pitches for repeatable installation
Earth bar / neutral bar versions (series B and G) for protective-earth distribution
CE certified; every model is identified by an order number
How to Choose
Highest current, 375 A, with 5×25 busbar: series A, 11 to 25 poles
225 A: series C (5×15) and series F (9×14)
150 A: series D (8×12), 4 to 12 poles, in blue or white. 135 A and 72 A: series E (8×12 and 6×8)
Earth bar / neutral bar: series B (3×17) and series G (8×12, earthing at one end)
Renewable energy systems, such as solar and wind power distribution
Electric vehicle charging infrastructure
Models & specifications
LEIPOLE busbar terminals (mini busbars) and earth bars / neutral bars for power and earth distribution inside control cabinets. Series A to H cover busbar sizes from 3×17 to 9×19 mm, up to 375 A, in 4 to 50 poles.
Match busbar size, rated current and number of poles before confirming a busbar terminal or earth bar.
How do I choose between series A to H?
Start with the rated current. Series A (5×25) is rated 375 A, series C and F are 225 A, series D is 150 A and series E is 72 A or 135 A depending on the busbar size. Series B and G are the earth bar / neutral bar versions. Then pick the pole count and pitch that fit your layout, and confirm the order number in the technical data.
What do the numbers in a name such as A-5×25/11 mean?
The first figures, 5×25, are the busbar cross-section in mm. The number after the slash is the pole count. A-5×25/11 is a 375 A terminal with a 5×25 busbar and 11 poles. In names ending in K, such as F9×14/5K, the number before K is the pole count. Every model also has its own order number.
What should I include in a busbar terminal inquiry?
Include the series and model or order number, rated current, number of poles, quantity and delivery destination. The Singapore team can then check the model against the current technical document.
