Why Choose the TE Connectivity M4/6.D2.1.N 1SNA125126R0300 Terminal Block?
The TE Connectivity M4/6.D2.1.N 1SNA125126R0300 is a blue double-deck screw clamp feed-through terminal block designed for compact signal wiring in industrial control and automation systems. Part of the established TE Connectivity Entrelec SNA terminal block series, it combines two connection levels within a narrow footprint to help maximise wiring density inside electrical panels.
Designed around reliable screw clamp termination technology, the M4/6.D2.1.N supports conductors up to a nominal 4 mm² / 12 AWG and provides a maximum contact current rating of 32 A. Its 800 V AC operating voltage and robust polyamide construction make it suitable for demanding industrial signal and control applications.
With a compact 6 mm spacing and integrated partition configuration, this terminal block is particularly useful where numerous test sockets are required, helping reduce the need for separate circuit separators. Its DIN rail mounting and double-deck arrangement provide an efficient solution for high-density machine control, process automation and electrical panel wiring.
