Description

Presentation
PEN junction block 2 poles 145-160A designed to centralize the PEN conductor (combined neutral and earth) in electrical panels. Enables reliable power distribution and continuity of protective earthing in industrial and commercial installations.

Electrical characteristics
  • Maximum current: 160 A (Copper) / 145 A (Aluminium)
  • Connection: compatible with Copper (Cu) or Aluminium (Al)
  • Configuration: 2 poles for PEN conductor (combined neutral + earth)
  • Primary cross-section range:
    • 2.5 to 4 mm² : torque 4 Nm
    • 6 to 50 mm² : torque 12 Nm
  • Rated voltage: 1000 V AC / 1500 V DC
  • Conductive grease: included to optimize contact
  • Standard: compliant with EN60947-7-1

Physical characteristics
  • Housing: PA66 self-extinguishing V0, removable cover
  • Conductive body: tinned aluminium
  • Mounting: DIN rail or surface mounting
  • Number of poles: 2 (neutral and earth combined – PEN)
  • Outputs per pole: 2
  • Protection: IP20

Packing
  • Sold: unit
  • Box: 14 pieces
  • Carton: 308 pieces

Features
  • Function: centralizes the PEN conductor (combination of protective earth PE and neutral N) on a single terminal to ensure distribution and continuity of protection.
  • PEN conductor: use in TN-C network reduces the number of conductors and panel space; the PEN conductor must meet a minimum cross-section and must never be interrupted (compliance with NF C 15-100).
  • Applications: industrial and commercial installations, modular distribution panels, industrial enclosures requiring a reliable and secure PEN connection.
