The TE Connectivity 1SNA290211R0200, type DR2.5/10.4L, is a compact four-connection spring-clamp feed-through terminal block designed for space-efficient industrial control and automation wiring. Part of the TE Connectivity / ENTRELEC SNA Miniblocks range, it combines a compact angled design with front conductor entry and convenient mounting on TH 15-5.5 DIN rail.
The spring-clamp connection system maintains consistent contact pressure independently of the installer and automatically compensates for conductor creep. This provides a dependable, maintenance-efficient connection while eliminating the need to apply or periodically check screw tightening torque. Four connection points allow multiple conductors to be interconnected through one compact terminal block.
Rated at 24 A and 800 V, the DR2.5/10.4L supports rigid conductors from 0.12–4 mm² and flexible conductors from 0.12–2.5 mm². Its 10 mm width, grey housing and front-entry wiring arrangement make it particularly suitable for compact terminal assemblies in industrial electrical panels.
Spring-clamp technology provides a consistent clamping force that is not dependent on installer-applied tightening torque. Automatic compensation for conductor creep helps maintain dependable electrical contact over time, making the DR2.5/10.4L well suited to industrial installations where connection reliability and efficient maintenance are important.
With four connections, front wiring access and a compact 10 mm profile, the 1SNA290211R0200 enables several conductors to be connected within a small DIN rail footprint. Its TH 15 mounting format makes it particularly useful for compact machinery, instrumentation and automation assemblies.
