TE Connectivity 1SNA115485R0200 MA2.5/5.1 is a grey 2.5 mm² ENTRELEC SNA screw-clamp feed-through terminal block with an integrated partition, rated at 24 A and 1000 V IEC for industrial signal wiring.
£1.25
The TE Connectivity 1SNA115485R0200, designated MA2.5/5.1, is a grey 2.5 mm² screw-clamp feed-through terminal block with an integrated partition from the ENTRELEC SNA range. The partition provides additional physical separation within the terminal assembly while retaining the compact dimensions required for high-density industrial panel wiring.
Designed for signal circuits, the MA2.5/5.1 provides a 24 A IEC current rating and 1000 V IEC voltage rating. Its screw terminals accommodate flexible conductors from 0.22–2.5 mm² and rigid stranded conductors from 0.2–4 mm², giving panel builders flexibility across common industrial conductor sizes.
The terminal occupies just 5 mm of DIN rail width and is manufactured from durable polyamide 6.6 with UL 94 V-0 flammability performance and IP20 protection. It mounts on G32, TH35-7.5 and TH35-15 DIN rails and is supplied in a pack quantity of 50.
The MA2.5/5.1 combines a conventional screw-clamp feed-through connection with an integrated partition, providing additional physical separation between adjacent parts of a terminal assembly. This configuration is particularly useful where panel designers require compact wiring alongside improved circuit organisation and separation.
With a 24 A IEC rating, 1000 V IEC voltage rating and 8 kV impulse withstand capability, the terminal provides dependable electrical performance while occupying only 5 mm of DIN rail width. Its wide DIN rail compatibility also makes it straightforward to integrate into both new and existing ENTRELEC SNA assemblies.
