Why Choose the TE Connectivity M4/8.SFD Fuse Terminal Block 1SNA115663R2300?
The TE Connectivity M4/8.SFD 1SNA115663R2300 is a grey fused DIN rail terminal block designed to combine secure conductor termination with convenient circuit protection in industrial control panels, machinery and automation systems. Part of the established TE Connectivity ENTRELEC SNA series, it provides a compact and serviceable solution for protected electrical and control circuits.
This terminal block uses a reliable screw connection and incorporates a lever-operated fuse disconnect arrangement. It accepts commonly used 5 × 20 mm and 5 × 25 mm fuses, allowing circuit protection to be integrated directly into the terminal strip while enabling straightforward fuse inspection and replacement.
Rated at 6.3 A and 400 V IEC, the 1SNA115663R2300 supports conductor sizes from 0.5–6 mm² and 12–22 AWG. Its compact 8 mm terminal width, polyamide insulation and UL 94 V-0 flammability classification make it well suited to professional industrial panel building and machine wiring applications.
