Why Choose the TE Connectivity M4/6.SNBT1.V0 Disconnect Terminal Block?
The TE Connectivity M4/6.SNBT1.V0 is a compact disconnect terminal block designed to provide reliable electrical connections for signal and control circuits in industrial control panels and automation systems. Part of the established ENTRELEC SNA screw-clamp terminal block series, it combines a space-saving 6 mm pitch with a manually operated disconnect blade for convenient circuit isolation and testing.
The M4/6.SNBT1.V0 features 2 positions on a single level and accepts conductors from 0.5 to 4 mm². The screw-clamp connection system provides secure conductor termination, while the integrated disconnect blade allows the circuit to be opened without removing the wiring from the terminal block.
With a 20 A IEC current rating, 400 V AC operating voltage and 4 kV impulse withstand voltage, the 1SNA195438R1300 is suited to a wide range of industrial signal and control applications. Its beige polyamide 6.6 housing has a UL 94 V-0 flammability rating and supports G32, TH35-7.5 and TH35-15 DIN rail mounting.

Convenient Circuit Isolation for Industrial Control Systems
Disconnect terminal blocks provide an efficient way to isolate individual circuits without removing the conductors from the terminal assembly. The M4/6.SNBT1.V0 incorporates a manually operated disconnect blade that can be operated by hand or with a screwdriver, making circuit isolation and maintenance more convenient.
The compact 6 mm pitch allows high terminal density on DIN rail installations, while the screw-clamp connections accommodate conductors up to 4 mm². The terminal block also shares the same profile as compatible M4/6 feed-through terminals, helping maintain aligned marking across an installation.
Typical Applications
- Industrial electrical control panels.
- PLC and automation control systems.
- Signal and instrumentation circuits.
- Machine control cabinets.
- Industrial process control systems.
- Electrical panel building and maintenance.
