Why Choose the TE Connectivity M4/6.SNB 1SNA115686R1300 Disconnect Terminal Block?
The TE Connectivity M4/6.SNB 1SNA115686R1300 is a compact and dependable 6 mm screw-clamp disconnect terminal block designed for switching, isolating and testing signal circuits in industrial electrical panels. Part of the established ENTRELEC SNA series, it combines secure screw termination with a blade-type disconnect mechanism for convenient circuit separation during commissioning, maintenance and fault finding.
This M4/6.SNB version features a grey body with a long grey disconnect blade, providing a clear and accessible means of opening an individual circuit without removing its connected conductors. The single-level, two-position construction occupies only 6 mm of DIN rail width, making it well suited to high-density control-panel installations.
With an IEC rating of 20 A at 400 V and conductor capacity up to 4 mm² / 10 AWG, the 1SNA115686R1300 provides reliable connectivity for industrial signal circuits. Its polyamide 6.6 housing, IP20 protection and compatibility with G32, TH35-15 and TH35-7.5 DIN rails make it a versatile solution for machinery, automation and instrumentation systems.

Reliable Signal Circuit Isolation and Switching
Disconnect terminal blocks provide a convenient way to open an individual electrical circuit while leaving the field wiring securely terminated. The M4/6.SNB uses a blade-type disconnect mechanism that allows technicians to separate the circuit during testing, commissioning or maintenance, reducing the need to repeatedly disconnect and reconnect conductors.
The long grey blade provides accessible manual switching while the screw-clamp terminals maintain secure conductor connections. Combined with its compact 6 mm profile and broad DIN rail compatibility, the M4/6.SNB is particularly useful for organised signal wiring in industrial control, automation and instrumentation panels.
Typical Applications
- Industrial control and automation panels.
- Signal circuit isolation and switching.
- PLC input and output wiring.
- Instrumentation and measurement circuits.
- Machine control and OEM equipment.
- Commissioning, maintenance and diagnostic circuits.
