Why Choose the TE Connectivity MA2.5/5.D2 Double-Deck Terminal Block?
The TE Connectivity 1SNA115490R1300 MA2.5/5.D2 is a compact 2.5 mm² double-deck feed-through terminal block designed for high-density signal wiring in industrial control panels, machinery and automation systems. Part of the established ENTRELEC SNA series, it combines two independent circuits within a narrow 5 mm-wide terminal, helping panel builders maximise available DIN rail space.
The MA2.5/5.D2 provides two connection levels, two circuits and four poles using proven screw-clamp termination technology. Its double-deck configuration allows two independent feed-through circuits to occupy the footprint normally associated with a single terminal level, making it particularly useful where panel space and wiring density are important considerations.
With an IEC current rating of 24 A and an IEC voltage rating of 630 V, the MA2.5/5.D2 provides dependable electrical performance for industrial signal circuits. The terminal accepts a nominal 2.5 mm² conductor size, mounts on G32, TH35-15 and TH35-7.5 DIN rails, and features a durable grey polyamide 6.6 housing with IP20 protection.

Space-Saving Connections for Industrial Control Systems
Double-deck feed-through terminal blocks provide two independent electrical circuits in the footprint of a narrow DIN rail terminal, allowing panel builders to significantly increase wiring density without sacrificing accessibility. The TE Connectivity MA2.5/5.D2 uses two separate connection levels so that conductors can be routed efficiently through control and signal circuits while maintaining clear circuit separation.
Its screw-clamp termination provides secure and durable conductor connections, while the compact 5 mm spacing makes the terminal particularly useful in densely populated automation cabinets. Compatibility with symmetrical and asymmetrical DIN rail formats further simplifies integration into industrial machinery, process control and electrical panel assemblies.
Typical Applications
- Industrial electrical control panels.
- PLC input and output wiring.
- High-density signal terminal assemblies.
- Machine control and automation systems.
- Instrumentation and process control panels.
- OEM machinery and electrical panel building.
