WAGO 2003-6641 Multilevel Installation Terminal Block 3-Level NTi/L/PE 20A 2.5mm

The WAGO 2003-6641 is a 3-level multilevel installation terminal block from the TOPJOB S 2003 Series, combining neutral (NTi), line (L), and protective earth (PE) terminations in a single DIN-35 rail-mounted unit. It uses Push-in CAGE CLAMP® technology to accept solid and fine-stranded copper conductors from 0.25 to 4 mm² across 5 clamping units, rated 20 A and 250 V (potential-ground) / 400 V (potential-potential) per IEC/EN 60947-7-1.

Features and benefits:

• Push-in CAGE CLAMP® accepts solid and ferrule-terminated conductors directly without tools; operating tool used for fine-stranded push-in insertion.
• 3-level NTi/L/PE layout consolidates neutral, line, and earth terminations into one 5.2 mm wide block, reducing panel space.
• Polyamide (PA66) housing with UL94 V0 flammability rating for fire-safe enclosure installations.
• Approved to UL 1059, CSA C22.2 No. 158, and CCA/EN 60947; EU and UK Declarations of Conformity issued by WAGO.
• Wide continuous operating range of -60 to +105 °C suits demanding industrial and building environments.

Applications:

• Grouping NTi/L/PE terminations in domestic and commercial distribution boards.
• Wiring control cabinets and switchgear panels where neutral, line, and earth share one compact DIN-rail block.
• Connecting mixed solid and fine-stranded copper conductors (0.25 to 4 mm²) in building installation circuits.
• Space-constrained DIN-35 rail assemblies requiring 3-level termination within a 5.2 mm pitch.
