£1.10
The TE Connectivity 1SNA115265R2400 is an MS4/6 feed-through screw clamp terminal block designed for reliable signal connections in industrial electrical control panels, machinery and automation systems. Part of the established ENTRELEC SNA terminal block series, it combines secure screw termination with a compact DIN rail format for dependable and organised panel wiring.
The MS4/6 provides one feed-through circuit with two connection positions and has a rated conductor cross-section of 4 mm². Its IEC electrical ratings of 32 A and 630 V AC make it suitable for a broad range of industrial signal and control circuits, while an impulse withstand rating of 4 kV supports reliable operation in professional electrical installations.
With a narrow 6 mm spacing and dimensions of 41 × 6 × 31 mm, the 1SNA115265R2400 helps maximise available DIN rail space. Its grey polyamide housing, IP20 protection rating and compatibility with G32, TH35-7.5 and TH35-15 DIN rails make it a versatile choice for industrial panel builders and automation engineers.
Feed-through terminal blocks provide a secure and organised connection between field wiring and electrical control equipment. Screw clamp technology maintains firm conductor contact while allowing connections to be installed, inspected and serviced using conventional tools, making it well suited to industrial panel building and machinery wiring.
The ENTRELEC MS4/6 combines this proven connection method with a compact 6 mm profile and compatibility with several common DIN rail formats. Its 4 mm² conductor capacity and industrial electrical ratings make it suitable for control, signal and automation circuits where reliable connections and efficient use of panel space are important.
