Why Choose the TE Connectivity 1SNA115340R0300 MB2x70/10.L4 Double Distribution Terminal Block?

The TE Connectivity 1SNA115340R0300, also identified as the ENTRELEC MB2x70/10.L4, is a robust DIN rail-mounted distribution terminal block designed for organised electrical distribution in industrial control panels, machinery and automation systems. As part of the established ENTRELEC SNA screw-clamp distribution terminal range, it provides a practical solution for distributing higher-capacity incoming connections to multiple outgoing circuits.

The MB2x70/10.L4 is a double distribution block configuration designed around 70 mm² incoming connections and 10 mm² distribution terminals. Its screw-clamp connection technology provides secure conductor retention, while the single-level modular construction allows straightforward integration into industrial electrical assemblies.

With a 10 mm² nominal cross-section, an 8 kV rated impulse withstand voltage and compact dimensions of approximately 68 × 103 × 44.2 mm, the 1SNA115340R0300 provides a dependable solution for industrial distribution duties. The block mounts on G32, TH35-7.5 or TH35-15 DIN rails, allowing flexible integration into new and existing electrical cabinets.
