The TE Connectivity 1SNA115192R0400 is an ENTRELEC M4/6.4 grey screw clamp feed-through terminal block with test access designed for signal and control wiring in industrial electrical panels and automation systems. Part of the established TE Connectivity ENTRELEC SNA series, it provides a secure two-position connection while allowing convenient circuit testing and diagnostics without disturbing the installed wiring.
The M4/6.4 is a single-level, single-circuit feed-through terminal block with two screw-terminal connection positions and a compact 6 mm pitch. It is designed for conductors up to 4 mm² and 10 AWG, combining reliable screw-clamp termination with a compact footprint suited to densely populated control cabinets.
With an IEC current rating of 32 A and an IEC voltage rating of 800 V, the 1SNA115192R0400 provides dependable electrical performance for industrial signal and control circuits. Its grey polyamide 6.6 housing, IP20 protection and compatibility with G32, TH35-7.5 and TH35-15 DIN rails make it a versatile terminal for professional panel building.
Feed-through terminal blocks provide an organised method of connecting incoming and outgoing conductors within electrical panels. The M4/6.4 combines dependable screw-clamp termination with test access, allowing maintenance engineers to perform measurements and diagnostic checks while keeping the permanent field wiring securely connected.
Its compact 6 mm pitch, 32 A IEC current rating and conductor capacity up to 4 mm² make the M4/6.4 particularly suitable for signal, control and automation circuits where both reliable connectivity and straightforward testing are required.
