Overview

2-phase pin busbar (M6) for dual-phase modular systems. Constant 17.8 mm pitch with compact pin 4 mm × 11.5 mm. Standard lengths 210 mm (12 modules), 1000 mm (54 modules) and 1016 mm (56 modules). Cross-sections 8/10/13/16 mm² cover 50–80 A reference current. Finger-safe, color-coded copper design ensures tidy wiring and low contact resistance. Complies with IEC 60664 and EN/IEC 60439-1.

Key Features

  • Pin geometry—secure contact in compact enclosures; ideal for dual-phase layouts.
  • Rapid installation versus loose jumpers; consistent module spacing.
  • Finger-safe insulation & color coding to reduce wiring errors.
  • Cut-to-length by module count or by the meter to fit your panel.
  • Also known as a two-phase pin rail for modular M6 devices.

FAQ

What is the difference between 1-phase and 2-phase pin busbars?
Both use 17.8 mm pitch and 4×11.5 mm pins for M6 devices. The 2-phase version is optimized for dual-pole layouts and offers 56 modules at 1016 mm (vs 57 for many 1-phase rails).
How do I select cross-section and current?
Typical mapping: 8 mm² ≈ 50 A; 10 mm² ≈ 63 A; 13 mm² ≈ 70 A; 16 mm² ≈ 80 A. Validate against device data and ambient conditions.
Can I order custom lengths?
Yes—provide target module count, total length, and quantity. We can supply pre-cut rails to reduce on-site work.
