1sna195490r1400 – ma2.5/5.d2.vo

Why Choose the TE Connectivity 1SNA195490R1400 MA2.5/5.D2.V0 Feed-Through Terminal Block?

The TE Connectivity 1SNA195490R1400 is an MA2.5/5.D2.V0 two-level feed-through screw-clamp terminal block designed for signal wiring in industrial control panels, machinery and automation systems. Part of the established TE Connectivity ENTRELEC SNA range, it combines a compact 5 mm pitch with two-level construction to support space-efficient wiring within modular terminal assemblies.

The MA2.5/5.D2.V0 provides a nominal wire size of 2.5 mm² and supports rigid stranded conductors from 0.2–4 mm² and flexible conductors from 0.22–2.5 mm². Its screw-terminal connection system provides secure conductor retention, while the terminal is rated at 24 A and 630 V according to IEC specifications.

Designed for flexible panel integration, the 1SNA195490R1400 mounts on G32, TH35-7.5 or TH35-15 DIN rail. Its beige Polyamide 6.6 housing carries a UL 94V-0 flammability rating and IP20 protection, while an operating temperature range of -55–110 °C supports use in demanding industrial environments.

Space-Efficient Two-Level Feed-Through Connections

Two-level terminal blocks allow multiple conductor connection points to be arranged vertically, reducing the DIN-rail length required for complex control and signal wiring. The MA2.5/5.D2.V0 combines this space-saving arrangement with established screw-clamp technology, providing secure and serviceable conductor connections within a compact 5 mm terminal width.

The TE Connectivity ENTRELEC MA2.5/5.D2.V0 is designed specifically for signal circuit applications and supports multiple common DIN-rail profiles. Its broad conductor acceptance, 24 A IEC rating and robust Polyamide 6.6 housing make it well suited to densely populated industrial panels where connection reliability and efficient use of space are important.
