Technical data

01 / PRODUCT VIEW

The F-3L M5 series uses a 17.8 mm device pitch with 11 mm-wide, 11.5 mm-long fork contacts. Published configurations cover 210, 1000 and 1016 mm lengths, 12 to 57 modules, conductor cross-sections from 8 to 16 mm² and reference currents from 50 to 80 A. The drawing identifies the repeating L1, L2 and L3 fork sequence for three-phase distribution.

04 / APPLICATIONS

Where F-3L M5 busbars are used

Three-phase distribution boards

Common-feed connections across compatible three-phase modular protective devices with M5 terminals.

Control panels

Organized three-phase power distribution where 17.8 mm pitch and the smaller M5 fork geometry are required.

OEM panel assemblies

Repeat panel builds selected by Article No., cross-section, module count and finished length.

05 / RESOURCES

F-3L M5 documents and product support

Use the published model table and dimension drawing for initial selection, then request controlled documentation with your enquiry.

What changes between F-3L M5 order models?

The published Article No., conductor cross-section, module count, overall length and reference current vary by model. The 17.8 mm pitch, 11 mm fork width and 11.5 mm fork length remain the same in the supplied table.

How should I select the F-3L M5 busbar?

Confirm the connected device has M5 terminals and the required L1/L2/L3 phase sequence, then select the cross-section, length, module count and reference current from the published model matrix.
