F2 T-Junction Boxes FAQ
Product questions
Find answers about fit, wiring and product differences.
F2 T-Junction Boxes
01Does the T layout define the electrical connection?
No. It defines the cable-entry directions. Match the terminal layout to the conductors that need to join inside the box.
02What space is needed around the F2-3T?
Allow for the body, opening the cover and tightening the entries. Each cable also needs enough bend space outside the box.

F2-3T 3-Way Junction Box
01Which F2-3T order code matches my cable?
MN-11: 5–8 mm; MN-12: 9–12 mm. These ranges refer to cable outside diameter.
02Can I choose screw or quick-connect terminals for F2-3T?
Yes. Both terminal styles are available. The seal is chosen by cable outside diameter, while the terminal is chosen by conductor size and circuit requirements.
03Does F2-3T use the same terminals as the F3 series?
F2-3T has a 10 A specification and a 0.5–2.5 mm² conductor range. F3 is a separate range with different terminal and conductor options.
