Why Choose the TE Connectivity 1SNA110251R0500 DR4/6 Miniblock Terminal Block?
The TE Connectivity 1SNA110251R0500 is a compact DR4/6 grey feed-through screw clamp terminal block designed for reliable conductor connections in space-constrained industrial control panels and electrical enclosures. Part of the established TE Connectivity ENTRELEC SNA terminal block series, this miniblock combines proven screw clamp connection technology with a narrow format for efficient industrial wiring.
The DR4/6 is specifically designed for installation on TH15-5.5 miniature DIN rail, making it particularly useful where conventional full-size terminal blocks would occupy unnecessary panel space. Its single-level, two-connection feed-through configuration provides a straightforward method of joining conductors while maintaining an organised and serviceable wiring layout.
With a rated current of 30 A, rated voltage of 500 V and rated cross-section of 4 mm², the 1SNA110251R0500 provides substantial electrical capacity despite its compact dimensions. It accepts flexible conductors from 0.22–4 mm² and rigid conductors from 0.2–4 mm², making it suitable for industrial control, automation, machinery and electrical distribution applications.
