Why Choose the TE Connectivity M4/8.SFLT Fuse Terminal Block?
The TE Connectivity 1SNA115667R2700 M4/8.SFLT is a compact 4 mm² screw-clamp fuse terminal block with blown-fuse indication, designed for protecting and monitoring signal circuits in industrial control panels, machinery and automation systems. Part of the established ENTRELEC SNA series, it accommodates standard cylindrical fuses while providing convenient DIN rail installation.
The M4/8.SFLT is designed for 5 × 20 mm and 5 × 25 mm fuses and incorporates a blown-fuse indicator to help maintenance personnel identify an open fuse quickly. Its lever-operated fuse disconnect arrangement provides convenient access to the fuse while allowing the protected circuit to be isolated within the terminal assembly.
With an IEC rated current of 6.3 A, an IEC rated voltage of 400 V and a 4 kV impulse withstand rating, the M4/8.SFLT is suited to industrial signal and control applications. Its grey polyamide 6.6 housing is only 8 mm wide, supports conductors up to 6 mm² depending on conductor type, and mounts on G32, TH35-7.5 or TH35-15 DIN rails.
Key Advantages
- Integrated fuse protection provides individual circuit protection directly at the terminal strip.
- Blown-fuse indication helps technicians identify failed fuses during troubleshooting and maintenance.
- Accepts standard 5 × 20 mm and 5 × 25 mm cylindrical fuses.
- Lever-operated fuse disconnect provides convenient access and circuit isolation.
- Compact 8 mm-wide construction helps conserve valuable DIN rail space.

Circuit Protection with Convenient Fuse Status Indication
Fuse terminal blocks combine conductor termination and overcurrent protection within a single DIN rail component. The TE Connectivity M4/8.SFLT accepts either a 5 × 20 mm or 5 × 25 mm fuse, allowing an individual signal or control circuit to be protected directly at the terminal strip without requiring a separate panel-mounted fuse holder.
The integrated blown-fuse indication helps maintenance personnel locate an open fuse more efficiently, while the lever-operated fuse carrier provides convenient access when inspection or replacement is required. Combined with secure screw-terminal connections and an 8 mm-wide housing, the M4/8.SFLT provides a practical solution for protected signal circuits in densely populated industrial control cabinets.
Typical Applications
- Industrial control and automation panels.
- PLC input and output circuit protection.
- Instrumentation and signal circuits.
- Machine control cabinets.
- Process automation and monitoring systems.
- Individual fused circuits in DIN rail terminal assemblies.
