Why Choose the TE Connectivity 1SNA110491R1700 DR4/6.1 Miniblock with Partition?
The TE Connectivity 1SNA110491R1700 is a grey DR4/6.1 screw clamp feed-through miniblock with partition designed for compact conductor connections in industrial control panels, junction boxes and automation equipment. Part of the ENTRELEC SNA terminal block range, its miniature construction helps save valuable rail space while providing secure and maintainable electrical connections.
The DR4/6.1 has a 4 mm² rated cross-section and accepts flexible conductors from 0.22–4 mm² and rigid conductors from 0.2–4 mm². Its integrated partition provides additional separation within the terminal assembly, while the compact 6 mm spacing makes it particularly suitable for installations where enclosure space is limited.
With a 30 A rated current and 500 V rated voltage, the 1SNA110491R1700 delivers dependable performance for industrial signal and control wiring. Unlike larger standard DIN rail terminal blocks, the DR4/6.1 is designed for the compact TH15-5.5 15 × 5.5 mm mounting rail in accordance with IEC 60715.

Compact Connections for Industrial Control Systems
Miniblock terminal blocks provide the same organised conductor termination principles as conventional terminal blocks while reducing the amount of mounting space required. The TE Connectivity DR4/6.1 uses screw-clamp technology to provide a secure electrical connection, while its integrated partition assists with separation within compact terminal assemblies.
The DR4/6.1 is designed for 15 mm TH15-5.5 minirail rather than standard 35 mm DIN rail, making it particularly useful in small junction boxes, marshalling panels, PLC wiring assemblies and other space-constrained installations. Its 4 mm² conductor capacity and compact 6 mm width provide a practical balance between wiring capacity and installation density.
Typical Applications
- Industrial electrical control panels.
- Compact junction and marshalling boxes.
- PLC and automation wiring systems.
- Signal and instrumentation circuits.
- Machine control and production equipment.
- Space-constrained electrical enclosures.
