Why Choose the TE Connectivity M16/12.NT 1SNA125128R1500 Neutral Disconnect Terminal Block?
The TE Connectivity M16/12.NT 1SNA125128R1500 is a robust blue neutral disconnect screw-clamp terminal block from the Entrelec SNA range, designed for secure neutral conductor connection and convenient circuit isolation in industrial electrical panels. Its disconnect functionality makes it particularly suitable for distribution, control and automation systems where neutral circuits may need to be isolated for testing, commissioning or maintenance.
Designed around a 16 mm² rated cross-section, the M16/12.NT uses proven screw-clamp connection technology to provide dependable conductor retention. It accepts flexible conductors from 2.5–16 mm² and rigid conductors from 2.5–25 mm², providing useful flexibility for industrial panel wiring.
The terminal block is rated at 76 A for the main circuit and 400 V, with a rated impulse withstand voltage of 6000 V. Its 12 mm spacing and compatibility with G32 and TH35 DIN rail profiles make it well suited to modular electrical distribution assemblies where reliability, accessibility and efficient installation are essential.
