August 21, 2008 – WAGO's DIN-rail mount terminal blocks, ranging from the 280 Series to 285 Series POWER CAGE CLAMP, now carry a 100 kA Short Circuit Current Rating (SCCR) when used with appropriate fuses. The SCCR originates from changes enacted by the National Electric Code and is represented as 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. “The 100 kA rating for WAGO terminal blocks ensures that our blocks will continue to serve motor control, variable frequency drives and control panels that require higher SCCR ratings,” said Michelle Goeman, Product Manager – Terminal Blocks & Electronic Interface.WAGO is the worldwide leader in spring pressure connection technology that eliminates loose wires as a result of vibration and temperature cycling, as well as provides highly reliable, corrosion-resistant and maintenance-free connections.
