ABB expands SNK range to enhance flexibility and installation efficiency

New compact pluggable terminal blocks can reduce mounting time by up to 90%

Hannover, April 13, 2015. ABB, the leading power and automation technology group, has launched the new pluggable terminal blocks series which helps industrial equipment manufacturer reduce installation efforts and optimize inventory levels.  Mounting and testing time is reduced by connecting subassemblies with pluggable terminal blocks and harnesses. The pluggable terminal blocks enable easy on site configuration and eliminate the need to stock a vast range of preconfigured solutions.

 “The new SNK pluggable range has been developed to help customers increase their productivity by optimizing the factory commissioning and secure their installation on-site”, says Frederic Stuckelberger, Connection Product Group Manager, in ABB´s Low Voltage Products Division. “Instead of wiring one terminal at a time, cables can be easily combined into assembled wiring harnesses equipped with plugs. Thus all the manufacturing, testing and commissioning operations are optimized, costs are saved and labor time is reduced by up to 90%.”

Reliable in harsh conditions.

The new range is particularly suited for applications where products can withstand harsh conditions, such as marine, switchgears, elevators or railways. It has successfully passed the most severe vibration, shock, temperature rise and vibration tests.   

Cost effective solutions

ABB pluggable terminal blocks offer a 15% footprint reduction compared to market average. The optimized size of the plugs provide larger marking surfaces for better visibility and identification of circuits. It is easy to create female plug assemblies without tooling from 2 to 15 poles by using only 2 plug variants which will reduce the stock of unitary plugs by up to 30%. The sub-assemblies of the industrial equipment can also be easily disconnected for transportation.

Safety and protection

The installation on-site is 100% secured thanks to the error-free coding system. Creating a coding sequence prevents a group of plugs from being inserted into the wrong circuits: just put a coding peg in one terminal block and cut the pin on the plug just opposite. A locking device can also be added to prevent any risk of break in connection in case of accidental wire pulling (additional safety device). It has an automatic locking function (just one click!) and locks safely simultaneously 2 to 8 plugs with only one locking device. The version with cable clamp can be used to group several cables together.

The SNK pluggable terminal blocks in brief

The SNK series pluggable terminal blocks comprises the PI-Spring technology and the screw clamp technology. SNK pluggable terminal blocks combine the benefits of SNK smart connections with the flexibility and performances of the plug-in connection The connecting capacity is going from 0.2 to 6 mm² (26 to 10 AWG).
