Overview

Single pole 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) × 12.5 mm (length), and standard lengths 210 mm (12 modules), 1000 mm (54 modules) and 1016 mm (57 modules). Color-coded insulated copper enables quick identification, low contact resistance and reliable 1-phase 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.
  • M6 screw terminals deliver secure, low-resistance joints and reduced heat rise.
  • 17.8 mm pitch aligns with 18 mm modular devices.
  • Finger-safe insulation improves protection and wiring confidence.
  • Custom cutting by module count or by the meter for panel fit.
  • Also called a single-phase busbar or 1-phase busbar for modular systems.

FAQ

Is “single pole busbar” the same as “single-phase busbar”?
Yes—both refer to a 1-phase busbar used to bridge adjacent poles on modular devices.
How do I pick the cross-section?
Guideline: 8 mm² ≈ 50 A, 10 mm² ≈ 63 A, 13 mm² ≈ 70 A, 16 mm² ≈ 80 A. Verify with device specs and ambient temperature.
What standard lengths are available?
210 mm (12 modules), 1000 mm (54 modules), and 1016 mm (57 modules). Custom cuts available on request.
