1sna115338r2500 – mb70/10.l8 dist term block 2×4

Why Choose the TE Connectivity 1SNA115338R2500 MB70/10.L8 Distribution Terminal Block?

The TE Connectivity 1SNA115338R2500, also identified as the ENTRELEC MB70/10.L8, is a heavy-duty DIN rail-mounted distribution terminal block designed to distribute an incoming high-capacity conductor connection across multiple outgoing circuits. The MB70/10.L8 configuration combines one 70 mm² stud connection with eight internally commoned 10 mm² terminals, providing an efficient distribution point for industrial control panels, machinery and electrical distribution systems.

As part of the established ENTRELEC SNA distribution terminal range, the MB70/10.L8 uses screw-clamp termination on its outgoing connections and provides a robust modular solution for panel builders and industrial electrical engineers. The internally commoned arrangement eliminates the need to create multiple external links between outgoing terminals, helping simplify wiring and maintain an organised panel layout.

With a 200 A current rating, an 800 V voltage rating and an 8 kV rated impulse withstand voltage, the 1SNA115338R2500 is suitable for demanding industrial distribution duties. Its grey housing measures approximately 68 × 104 × 44.2 mm and can be mounted on G32, TH35-7.5 and TH35-15 DIN rail formats.

Efficient Power Distribution for Industrial Control Panels

Distribution terminal blocks such as the TE Connectivity ENTRELEC MB70/10.L8 provide a convenient method of dividing a higher-capacity incoming electrical connection into multiple outgoing circuits. The internally commoned design reduces additional wiring and bridging requirements while creating a structured and accessible distribution point within the electrical panel.

The MB70/10.L8 is particularly useful where a large incoming conductor needs to supply several smaller circuits. Its combination of a 70 mm² stud connection and eight 10 mm² outgoing terminals supports efficient industrial power distribution while its DIN rail mounting allows straightforward integration alongside other terminal blocks and control components.

Typical Applications

• Industrial electrical distribution panels.
• Machine-building and OEM control cabinets.
• Power distribution within automation systems.
• Manufacturing and process-control equipment.
• Distribution from large incoming conductors to multiple branch circuits.
• DIN rail-mounted industrial electrical assemblies.
