Technical specifications Branching and sectionalizing terminal block 4×150 mm² – N0CE0026AL

Structure and materials

  • Base made of SMC (fiberglass) in red RAL 3020 with integrated phase-separating fins.
  • Active terminal parts made of brass Cu Zn 40 Pb 2, compliant with UNI EN 12165 CW 617 N, obtained by machining.
  • M22 brass terminal screws with recessed hexagon head and spring washers placed between screw and cable clamping plate.
  • Auxiliary M8 screws and washers in stainless steel to ensure mechanical strength and corrosion resistance.
  • Protective screen in transparent self-extinguishing polycarbonate fixed to the base by means of knurled-head threaded bushings.

Functions

  • Branching and sectionalizing terminal block for 4-way LV lines, suitable for aluminium cables up to 150 mm² and copper cables up to 95 mm².
  • Configuration designed for Enel street cabinets DS 4522, DS 4523, DS 4974 and DS 4549.
  • Clear identification of phases by letters R, S, T and neutral N; neutral terminals are highlighted in blue.
  • Dedicated holes for inserting electrical test probes on each terminal, accessible even with the protective screen installed.
  • Polycarbonate screen with R, S, T, N markings and central “dangerous voltage” warning triangle to protect the operator.

Compliance

The N0CE0026AL terminal block is designed in compliance with ENEL DS 4974 requirements for flame resistance (>80 points) and refers to ENEL Technical Specification Table DS 4533 matr. 286021 for use in street cabinets. The insulating material meets surface tracking resistance requirements PTI 500 according to IEC 60112, while the degree of protection IP00 is defined by CEI EN 60529.
