Why Choose the TE Connectivity 1SNA190003R2200 D120/42.FF Power Terminal?
The TE Connectivity 1SNA190003R2200 is a heavy-duty D120/42.FF feed-through power terminal block designed for high-current electrical distribution in industrial control panels, switchgear and power systems. Part of the established TE Connectivity ENTRELEC SNA terminal block range, it provides a robust connection point for large conductors where dependable power distribution is essential.
Designed for conductors up to 120 mm², the D120/42.FF combines a 269 A maximum contact current rating with an operating voltage of 600 V AC. Its two-position feed-through configuration provides a straightforward electrical path through the terminal, while the 42 mm spacing accommodates the substantial connection hardware required for high-current industrial wiring.
The 1SNA190003R2200 mounts directly onto standard TH35-7.5 or TH35-15 DIN rail and is supplied in grey for conventional panel identification. With an operating temperature range of -55–110 °C, it is engineered for demanding industrial environments and is particularly suitable for power distribution, machinery and high-current control cabinet applications.
