Product Model
235-551

Selling Points
- 1Automatic Clamping: The WAGO 235-551 terminal block uses the patented CAGE CLAMP mechanism, which automatically connects solid or stranded wires without special wire preparation.
- 2High Specific Pressure: The stainless-steel clamping mechanism exerts a high specific pressure that embeds the conductors into the soft tin of the current bar, creating a "gas-tight" connection.
- 3Corrosion Resistance: The terminal block is inherently corrosion-resistant due to its stainless-steel construction and the embedded conductors, ensuring long-lasting connections.
- 4Easy Installation: No special wire preparation like crimps, ferrules, or tinning is necessary, making installation quick and efficient.
- 5Proportional Clamping: The clamping force adjusts automatically to the conductor cross-section, ensuring a secure connection regardless of wire size.
