Smart connections with pluggable terminal blocks

The SNK series pluggable terminal blocks combine the benefits of our smart connections with the flexibility of the pluggable function. Pluggable technology brings modularity into the electrical installation allowing the combination of sub-assemblies and pre-wired harnesses that facilitate and considerably accelerate assembly test and factory commissioning. Qualified for worldwide markets, applications and for severe environments (including hazardous locations, railways, marine and solar applications etc.).
