Pin Type Busbar (M6) — 1-Phase, 8–16 mm²
• For MCBs/RCCBs with M6 terminals；pitch 17.8 mm；pin 4 × 11.5 mm
• Standard lengths 210 / 1000 / 1016 mm；modules 12 / 54 / 57
• Reference current 50–80 A；finger-safe insulation；IEC 60664 & EN/IEC 60439-1
Overview
Pin type busbar (M6) for modular devices such as MCBs and RCCBs. It uses a constant 17.8 mm pitch with compact 4 mm (pin width) × 11.5 mm (pin length), and standard lengths 210 mm (12 modules), 1000 mm (54 modules) and 1016 mm (57 modules). The finger-safe, color-coded copper design enables neat wiring, low contact resistance and reliable single-phase distribution. Compliant with IEC 60664 and EN/IEC 60439-1.

8 / 10 / 13 / 16 mm² • 50–80 A
Key Features
- Pin geometry provides secure, space-efficient connections for dense layouts.
- Fast installation—plug-style pins reduce wiring time versus loose jumpers.
- 17.8 mm pitch matches 18 mm modular spacing; 4×11.5 mm pins fit common M6 terminals.
- Finger-safe insulation & color coding reduce wiring errors and improve safety.
- Custom cutting by module count or by the meter for panel fit.
- Also called a pin busbar for 1-phase modular systems.
