The TE Connectivity M4/6.N.RS 1SNA125930R1500 is a blue spring-loaded screw-clamp feed-through terminal block designed for secure conductor connections in industrial control panels, energy systems and electrical distribution equipment. Part of the established Entrelec SNA terminal block range, it combines conventional screw termination with a spring-assisted contact arrangement designed to maintain dependable connection pressure.
With a nominal conductor cross-section of 4 mm² and a compact 6 mm pitch, the M4/6.N.RS provides one feed-through circuit with two connection points. Its main circuit is rated at 32 A, while the terminal accepts rigid conductors from 0.2–4 mm² and flexible conductors from 0.22–4 mm², making it suitable for a broad range of industrial wiring tasks.
The blue polyamide housing provides clear circuit identification and incorporates IP20 protection at the main terminals. Compatibility with G32, TH35-7.5 and TH35-15 mounting rails in accordance with IEC 60715 allows the terminal to be integrated into a wide variety of professional panel and switchgear configurations.
The M4/6.N.RS uses a safety-oriented spring-loaded screw-clamp design in which spring action helps maintain contact pressure even if the clamping screw is loosened. This connection principle provides a robust mechanical interface for demanding industrial and energy-sector installations while retaining the familiar installation method of a screw terminal.
Its 4 mm² nominal capacity, 32 A current rating and compact 6 mm footprint make the terminal suitable for building dense, organised terminal strips. The wide -55 to +110 °C operating temperature range further supports reliable service in industrial machinery, switchgear and automation equipment.
