Why Choose the TE Connectivity MA2.5/5.N 1SNA125486R0500 Blue Terminal Block?
The TE Connectivity MA2.5/5.N 1SNA125486R0500 is a compact blue 2.5 mm² feed-through screw-clamp terminal block from the Entrelec SNA series, designed for secure and space-efficient conductor connections in industrial control panels, machinery and automation systems. Its blue housing provides clear visual identification within terminal assemblies, making it particularly suitable for neutral and other designated circuit wiring.
The MA2.5/5.N combines proven screw-clamp connection technology with a compact 5 mm terminal spacing. It accepts flexible conductors from 0.22–2.5 mm² and rigid conductors from 0.2–4 mm², providing flexibility for control, signal and power distribution wiring while maintaining a high connection density on the DIN rail.
Rated at 24 A with an operating voltage of up to 1000 V AC, the terminal is engineered for dependable industrial service. It mounts on G32, TH35-7.5 and TH35-15 DIN rails and features an IP20-protected, flame-retardant polyamide 6.6 housing, making it a versatile choice for professional electrical panel construction.

Compact and Reliable DIN Rail Connections
Feed-through terminal blocks provide a secure point-to-point electrical connection while keeping panel wiring organised, accessible and easy to maintain. The MA2.5/5.N uses screw-clamp technology to retain conductors securely and provides convenient access for installation, testing and servicing.
Its narrow 5 mm profile is particularly valuable in densely populated electrical cabinets where DIN rail space is limited. The blue insulation provides immediate visual differentiation from standard grey terminals, helping panel builders create clearly organised neutral or colour-coded circuit groups.
Typical Applications
- Industrial electrical control panels.
- Neutral and colour-coded circuit connections.
- PLC and automation system wiring.
- Machine control cabinets.
- Switchgear and electrical distribution assemblies.
- Process control and instrumentation systems.
