Q3
Q3 ENERGIE has been developing and manufacturing innovative PV components in Germany since 2010. Our portfolio includes the QFire firefighter switch, customised AC and DC connection technology, and intelligent distribution and protection solutions for
⚡AC Box - AC Connection and Surge Protection Boxes for Commercial & Utility-Scale Systems TN-C | TN-C-S | 160 A | 250 A | 400 A | 630 A
They protect sensitive inverters and grid connection equipment through integrated surge protection (Type 1 + 2 + 3) and upstream fuse disconnectors. Each box is delivered as a ready-to-install custom build: all components pre-assembled, tested and ready to connect.
The design supports all common grid types (TN-C, TN-S, TN-C-S) and is suitable for large cable cross-sections (e.g. NYY-J 4 × 300 mm²). With high current-carrying capability and individual engineering, the AC box is a reliable solution against surge events – made in Germany in the Allgäu region.
