TE Connectivity 1SNA115649R0500 M4/8.D2.SFLJ is an 8 mm double-deck SNA screw-clamp fuse terminal block for 5 × 20 mm and 5 × 25 mm fuses, featuring blown-fuse indication and a 6.3 A, 500 V rating.
Why Choose the TE Connectivity M4/8.D2.SFLJ 1SNA115649R0500 Fuse Terminal Block?
The TE Connectivity M4/8.D2.SFLJ 1SNA115649R0500 is a compact double-deck screw-clamp fuse terminal block with blown-fuse indication designed for circuit protection and signal distribution in industrial control panels. Part of the proven ENTRELEC SNA screw terminal range, it combines a fuse-protected upper level with a feed-through lower level to provide two independent circuits within a space-saving DIN rail footprint.
The M4/8.D2.SFLJ accepts 5 × 20 mm and 5 × 25 mm cartridge fuses and incorporates a blown-fuse indicator to help maintenance personnel identify a defective protected circuit quickly. The fuse is not supplied with the terminal block, allowing the appropriate fuse rating to be selected for the application. Its screw-clamp connections provide secure, serviceable conductor termination for industrial wiring.
With a rated current of 6.3 A, rated voltage of 500 V and a compact width of only 8 mm, the 1SNA115649R0500 provides an efficient combination of circuit protection, indication and feed-through connectivity. Its grey thermoplastic housing, IP20 terminal protection and wide operating temperature range make it well suited to automation, machinery and process-control installations.
Key Advantages
Double-deck design provides two independent circuits within a compact DIN rail footprint.
Upper level provides fuse protection while the lower level provides a feed-through connection.
Compatible with 5 × 20 mm and 5 × 25 mm cartridge fuses.
6.3 A, 500 V rating suits industrial control and signal applications.
Compact 8 mm width helps maximise available DIN rail space.
Key Features
TE Connectivity / ENTRELEC SNA series fuse terminal block.
M4/8.D2.SFLJ double-deck configuration.
One fused upper circuit plus one independent feed-through circuit.
Blown-fuse indication for rapid fault identification.
Designed for 5 × 20 mm and 5 × 25 mm fuses.
Screw-clamp connection technology for secure industrial wiring.
6.3 A rated current and 500 V rated voltage.
Grey insulating housing with UL 94 V-0 flammability classification.
Reliable Fused Circuit Protection and Distribution
Fuse terminal blocks provide localised overcurrent protection directly at the terminal level, helping protect individual control, signal and instrumentation circuits while keeping panel wiring organised. The M4/8.D2.SFLJ combines this protection with a separate feed-through connection, allowing two independent circuits to occupy the same double-deck terminal position.
The integrated blown-fuse indicator helps reduce troubleshooting time by providing immediate visual identification when the fuse-protected circuit has operated. Combined with replaceable cartridge fuses and proven screw-clamp connection technology, the M4/8.D2.SFLJ provides a practical solution for industrial systems where compact installation, circuit protection and maintainability are important.
Typical Applications
Industrial control and automation panels.
PLC input and output circuit protection.
Instrumentation and signal circuits.
Machine control and OEM equipment.
Process-control and manufacturing systems.
Compact fused power and signal distribution.
