The 56.106.0653.0 is a current transformer disconnect terminal block (type WK6 TK P3/35) designed for use in electrical installations with spring connection technology. It accommodates fine stranded and solid conductors from 0.5 to 10 mm² (No. 20-8 AWG) and is rated for 400 V / 6 kV / 3 phase with a current capacity of 32 A at 600 V (UL/CSA ratings) and 45 A at 300 V (CSA ratings). The block features an 8 mm width and 12 mm wire strip length, providing compact integration on DIN rail mounting systems. It is commonly used in current transformer circuits for normal operation, measured value testing, transformer short circuit protection, and relay testing applications in industrial power distribution and control systems.
