Why Choose the TE Connectivity DR4/8.SF 1SNA110368R1200 Mini Fuse Terminal Block?
The TE Connectivity DR4/8.SF 1SNA110368R1200 is a compact screw clamp fuse terminal block designed to provide convenient circuit protection within industrial control panels, machinery and automation systems. Part of the established TE Connectivity ENTRELEC SNA series, this miniblock integrates a fuse holder directly into the terminal connection, helping reduce panel space while providing reliable overcurrent protection.
The DR4/8.SF accommodates both 5 × 20 mm and 5 × 25 mm fuses, allowing commonly used cartridge fuses to be incorporated directly into the terminal row. Its secure screw clamp connections accept flexible and rigid conductors from 0.5–4 mm², while the compact 8 mm spacing makes it particularly suitable for densely populated control cabinets.
Rated at 6.3 A and 630 V, the 1SNA110368R1200 provides dependable protection for control, signal and auxiliary circuits. It mounts on TH15-5.5 Minirail in accordance with IEC 60715 and features an IP20 grey polyamide housing, making it a practical solution for compact industrial terminal assemblies where individual fused circuits are required.

Compact Fused Circuit Protection for Industrial Panels
Fuse terminal blocks combine conductor termination and overcurrent protection within a single DIN rail component. The TE Connectivity DR4/8.SF allows a cartridge fuse to be installed directly in the terminal block, providing individual protection for control and auxiliary circuits without requiring a separate panel-mounted fuse holder.
The compact ENTRELEC miniblock format is particularly useful where DIN rail space is restricted. With its 8 mm width, TH15-5.5 Minirail mounting and support for both 5 × 20 mm and 5 × 25 mm fuses, the DR4/8.SF provides panel builders with a space-efficient and serviceable solution for protected circuit distribution.
Typical Applications
- Industrial electrical control panels.
- PLC input/output and control circuits.
- Sensor and instrumentation supply circuits.
- Machine building and OEM automation equipment.
- Process control and auxiliary circuits.
- Compact switchgear and Minirail terminal assemblies.
