ABB 1SNA110327R2100 Multi-Level Installation Terminal Block, 3-Level PE/N/L, Screw Clamp, 6 mm², Grey/Blue/Green-Yellow

This ABB installation terminal block combines three connection levels in one compact 17.8 mm housing, providing separate PE, N, and L terminations for efficient panel wiring. Unlike single-level blocks, it saves rail space and reduces wiring time for power distribution applications.

Highlights

• 3-level design: PE (green/yellow), N (blue), L (grey)
• Screw clamp connection for solid, stranded, and ferruled conductors
• Nominal cross-section 6 mm², accepts wires from 0.2 to 10 mm²
• Rated voltage 500 V, rated current 24 A (IEC)
• DIN rail mounting on TH35-7.5 or TH35-15
• Polyamide housing, UL 94 V-0 flammability rating

In daily use

The terminal block is installed on a standard DIN rail and wired with a screwdriver. Conductors are stripped to 10 mm and tightened to 0.8 Nm. The colour-coded levels help electricians quickly identify PE, N, and L connections, reducing wiring errors. The block is suitable for control panels, distribution boards, and machine building.
