TE Connectivity M4/6.D2.N 1SNA125271R2400 is a blue 4 mm² double-deck screw-clamp feed-through terminal block rated at 32 A and 800 V IEC for compact industrial DIN rail wiring.
Why Choose the TE Connectivity M4/6.D2.N 1SNA125271R2400 Double-Deck Terminal Block?
The TE Connectivity M4/6.D2.N 1SNA125271R2400 is a blue double-deck screw-clamp feed-through terminal block designed for compact and reliable conductor connections in industrial control panels, machinery and automation systems. Its two-level construction provides two independent circuits within a narrow terminal footprint, helping panel builders increase wiring density without sacrificing accessibility.
Designed around a rated cross-section of 4 mm², the M4/6.D2.N combines proven screw-clamp termination with a compact 6 mm pitch. The main circuit is rated at 32 A and 800 V under IEC specifications, making this terminal block suitable for demanding signal and control wiring applications where dependable electrical connections and efficient use of DIN rail space are important.
The terminal is manufactured from durable polyamide and provides IP20 protection at the main terminals. It accepts flexible conductors from 0.22–4 mm² and rigid conductors from 0.2–4 mm², while compatibility with G32, TH35-7.5 and TH35-15 mounting rails provides flexibility across a wide range of industrial panel designs.
Key Advantages
Double-deck design accommodates two independent circuits in a compact footprint.
6 mm pitch supports high-density control-panel wiring.
32 A IEC rated current for dependable industrial connections.
800 V IEC rated voltage provides strong electrical performance.
32 A rated current according to IEC specifications.
800 V rated voltage according to IEC specifications.
8 kV rated impulse withstand voltage.
IP20 degree of protection at the main terminals.
DIN rail mounting for professional panel installations.
Reliable High-Density Connections for Industrial Panels
Double-deck terminal blocks allow two independent electrical circuits to be connected vertically within the rail space normally occupied by a single terminal position. The M4/6.D2.N therefore helps reduce the overall length of terminal strips, making it particularly valuable in control cabinets where DIN rail space is limited.
Its screw-clamp connection system provides a robust mechanical and electrical interface for rigid and flexible conductors. Combined with an 800 V IEC voltage rating, 32 A IEC current rating and broad -55 to +110 °C operating temperature range, the terminal is well suited to reliable wiring in industrial automation, machinery and process-control equipment.
Typical Applications
Industrial electrical control panels.
High-density terminal strip assemblies.
PLC and automation control cabinets.
Machine building and OEM equipment.
Process-control and instrumentation wiring.
Signal and control circuit distribution.
