Overview

This fork-type Single Phase Busbar is engineered for M6 clamping screws and modular protection devices (MCBs/RCCBs). It uses a constant 17.8 mm pitch with fork width/length 12 mm for fast alignment and secure, low-resistance joints. Standard lengths include 210 mm (12 modules), 1000 mm (54 modules) and 1016 mm (57 modules). The conductor is copper with flame-retardant PVC insulation and a finger-safe profile (DIN EN 50274) to support safe, reliable single-phase distribution.

FAQ

What’s the difference between this 1-phase busbar and a four-pole busbar?
The 1-phase busbar bridges adjacent single-phase modular devices on one phase, while a four-pole busbar connects three phases plus neutral across a 4-pole layout.
Which cross-section should I select?
Choose by current and allowable temperature rise: 8 mm² ≈ 50 A, 10 mm² ≈ 63 A, 13 mm² ≈ 70 A, 16 mm² ≈ 80 A. Confirm against device and installation conditions.
What lengths and module counts are available?
210 mm (12 modules), 1000 mm (54 modules), and 1016 mm (57 modules) are standard; other cuts are available by request.
Is the busbar finger-safe?
Yes. When installed as specified, its insulated profile is finger-safe according to DIN EN 50274.
What torque should I apply to M6 terminals?
Use the terminal torque specified by the modular device manufacturer; the fork geometry maintains a secure, low-resistance joint at the rated torque.
