Overview
3P+N busbar (M6 fork-type) for modular devices such as MCBs and RCCBs. It uses a constant 17.8 mm pitch with fork 11 mm (width) × 13.5 mm (length), and standard lengths 210 mm (12 modules) and 1000 mm (54 modules). Color-coded insulated copper enables quick identification, low contact resistance and reliable three-phase-with-neutral distribution. Compliant with IEC 60664 and EN/IEC 60439-1.
M6 clamping screws
Cross-sections 8 / 10 / 13 / 16 mm²
Reference current 50–80 A
Key Features
- Fork geometry for quick install/removal without full disconnection.
- Integrated neutral path designed for 3-phase + N layouts; simplifies N bridging.
- M6 screw terminals deliver secure, low-resistance joints and reduced heat rise.
- Color-coded insulation aids phase/neutral identification and reduces wiring errors.
- 17.8 mm pitch aligns with 18 mm modular devices; 11×13.5 mm fork fits common terminals.
- Custom cutting by module count or by the meter for panel fit.
