The TE Connectivity 1SNA115523R0700, also identified as the ENTRELEC M4/8, is a grey 4 mm² screw-clamp feed-through terminal block designed for signal wiring in industrial control panels, machinery and automation systems. Part of the established ENTRELEC SNA series, it provides a secure two-position connection for joining conductors through a DIN rail-mounted terminal assembly.
The M4/8 features an 8 mm terminal spacing and uses proven screw-terminal technology for dependable conductor retention and straightforward servicing. Its profile is designed to simplify installations using alternating feed-through and fuse circuits, particularly when installed alongside compatible M4/8.SF fuse terminal blocks.
Rated at 26 A and 500 V to IEC specifications, the 1SNA115523R0700 supports flexible conductors from 0.22–4 mm² and rigid stranded conductors from 0.5–6 mm². Its polyamide 6.6 housing, UL94 V-0 flammability rating and wide operating temperature range provide a robust connection solution for professional industrial installations.
Feed-through terminal blocks such as the TE Connectivity ENTRELEC M4/8 provide a secure and organised method of joining conductors within industrial control cabinets. The single-level, two-position configuration creates a straightforward electrical path through the terminal, while screw-clamp technology provides reliable mechanical retention and convenient access during installation and maintenance.
The M4/8 is particularly useful where feed-through and fuse circuits are arranged alternately, as its profile complements the M4/8.SF fuse terminal design. Combined with its 26 A IEC current rating, 500 V IEC voltage rating and broad DIN rail compatibility, this makes the M4/8 a versatile choice for machinery, automation and industrial control-panel wiring.
