Why Choose the TE Connectivity 1SNA105055R2400 M6/8.SNB Disconnect Terminal Block?
The TE Connectivity 1SNA105055R2400 is an orange M6/8.SNB screw clamp disconnect terminal block designed for reliable circuit connection and isolation in industrial control panels, switchgear and automation equipment. Part of the ENTRELEC SNA series, it incorporates a blade disconnect mechanism that allows an individual circuit to be opened for testing, maintenance or troubleshooting without removing the connected conductors.
The M6/8.SNB combines proven screw-clamp termination with a compact 8 mm pitch and accommodates flexible conductors from 0.5–6 mm² and rigid conductors up to 10 mm². Its orange polyamide housing provides clear identification within densely wired electrical assemblies, while the disconnect blade can be operated by hand or with a screwdriver for convenient circuit isolation.
With an IEC rated current of 15 A and 400 V rated voltage, the 1SNA105055R2400 provides dependable performance for industrial signal and control circuits. The terminal mounts onto G32, TH35-7.5 and TH35-15 DIN rails and shares its profile with the M6/8 feed-through terminal block, helping maintain neat and aligned terminal assemblies.
