56.704.5155.0 is a WKFN 4 D2/2/35 DIN rail terminal block with screw connection designed for industrial control panel applications. It accommodates connectable conductors ranging from 14 to 10 AWG and features a Short Circuit Current Rating (SCCR) of 100 kA, significantly exceeding the UL 508A default value of 10 kA. The terminal block provides dimensional specifications including J=200, T=200, RK1=200, RK5=100, G=60, and CC=30, ensuring compatibility with standard DIN rail installations. This high SCCR rating offers increased flexibility and accuracy when qualifying industrial control panel installations under NEC Article 409 and UL 508A standards, allowing for more precise system-level short circuit current calculations and reducing the need for additional current-limiting devices.
