Why Choose the TE Connectivity 1SNA105032R1500 M4/6 Terminal Block?
The TE Connectivity 1SNA105032R1500, designated M4/6, is a red feed-through screw-clamp terminal block from the Entrelec SNA series. Designed for DIN rail mounting in industrial electrical installations, it provides a secure and serviceable connection for signal, control and automation wiring.
The M4/6 combines a compact 6 mm spacing with conductor capacity up to 4 mm² / 10 AWG. Its screw-terminal connection system provides dependable conductor retention, while compatibility with G32, TH35-15 and TH35-7.5 DIN rails allows flexible integration into a wide range of electrical cabinets.
With an IEC rating of 1000 V / 32 A and UL/CSA ratings of 600 V / 30 A, the red M4/6 combines compact dimensions with robust electrical performance. Its coloured housing is particularly useful where circuits or functions need to be visually distinguished within densely populated terminal assemblies.
