Difference Between 260-301 (2 Wire) and 260-331 (4 Wire) Terminal Block

260 Series terminal block, 2 wire din rail terminal, WAGO 260-301 replacement, cage clamp feed-through terminal, 1.5mm spring wiring connector

1. Core Structure Difference

  1. 260-301
  • 2 wiring holes: 1 wire in, 1 wire out
  • Only realize straight single-circuit connection
  • No shunting function, one wire pass through only
  1. 260-331
  • 4 wiring holes: 2 inlet + 2 outlet, all four holes same potential
  • Support parallel connection of up to 4 wires for circuit shunting
  • Replace small sub-wire box inside control cabinet

2. Same Common Parameters (Both Models)

  • Width: unified 8mm
  • Wire range: 0.08–1.5mm² / 28–16AWG
  • Rated current & voltage: 18A/400V IEC, 10A/300V UL
  • Material, temperature resistance, installation way identical
  • Full compatible accessories & certifications
  • Interchangeable installation position on DIN rail

3. How To Choose Correct Model

  • Pick 260-301 if you only need simple one-in-one-out straight wiring for single signal or single power line.
  • Pick 260-331 if you need to gather multiple wires to one potential point, for signal distribution and multi-line shunting in compact cabinets.
