Terminal blocks, interconnects earn 100 kA short circuit current rating

Select Wago Corporation Through-Panel and Chassis-Mount Terminal blocks and Interconnect devices have earned a 100 kA (short circuit current rating (SCCR) rating with appropriate fuses.


Select Wago Corporation Through-Panel and Chassis-Mount Terminal blocks and Interconnect devices have earned a 100 kA (short circuit current rating (SCCR) rating with appropriate fuses.

The newest Wago products with 100kA SCCR: 862 and 264 and Series Chassis-Mount Blocks, 826 and 828 Series Through-Panel Blocks, 831 Series Multi Connector System Pluggable Connector and X-ComS Pluggable Connector System.

Stemming from changes enacted by the National Electric Code, SCCR is represented by UL508A. SCCR ensures proper documentation of the maximum short circuit current a component, assembly or equipment can safely withstand when protected by a specific overcurrent protective device. For instance, a control cabinet's SCCR is the same as that of a component, in the cabinet's electrical distribution path, with the lowest SCCR.

Other Wago terminal blocks carrying 100kA SCCR include: 280 Series to 285 Series Power Cage Clamp models, TopjobS terminal blocks, X-Com) and 870 Series Cage Clamp Compact.

Wago offers spring pressure connection technology that eliminates loose wires resulting from vibration and temperature cycling, while providing highly reliable, corrosion-resistant and maintenance-free connections. Products include DIN-rail, PCB and chassis mount terminal blocks; signal conditioners; the Wago-I/O-Ssystem and more.
