1sna115480r1100 – m4/6 sntb.4a dep**
TE Connectivity M4/6.SNBT.4A 1SNA115480R1100 is a grey 4 mm² screw clamp disconnect terminal block with a blade disconnect mechanism and two test socket screws for industrial control, signal and measurement circuits.
Why Choose the TE Connectivity M4/6.SNBT.4A 1SNA115480R1100 Disconnect Terminal Block?
The TE Connectivity M4/6.SNBT.4A 1SNA115480R1100 is a grey screw clamp disconnect terminal block with blade disconnection and test sockets, designed for industrial control, measurement and signal circuits. Part of the established TE Connectivity ENTRELEC SNA series, it combines secure conductor termination with a convenient disconnect function for circuit isolation, testing and maintenance.
The M4/6.SNBT.4A uses double compression screw clamp connections together with a blade disconnect mechanism. The disconnect point allows a circuit to be opened without removing the connected conductors, while two integrated test socket screws provide convenient access for measurement and diagnostic work during commissioning, servicing and fault finding.
Designed around a 4 mm² rated cross-section and compact 6 mm spacing, the M4/6.SNBT.4A provides a space-efficient solution for disconnect and test circuits. Its DIN rail compatibility includes G32, TH35-7.5 and TH35-15 profiles, while a broad operating temperature range of -55 to +110 °C supports use across demanding industrial environments.
Key Advantages
- Blade disconnect function enables circuit isolation without removing field wiring.
- Two integrated test socket screws simplify electrical measurement and diagnostic work.
- Double compression screw clamp technology provides secure and maintainable conductor connections.
- 4 mm² rated cross-section in a compact 6 mm terminal width.
- Suitable for conductor sizes from 0.5–4 mm² in typical connection configurations.
- Compatible with G32, TH35-7.5 and TH35-15 DIN rails for flexible panel installation.

Convenient Circuit Isolation and Testing
Disconnect terminal blocks allow technicians to isolate individual circuits without disturbing permanent field wiring. The M4/6.SNBT.4A incorporates a blade disconnect mechanism between its conductor connections, making it particularly useful in control, instrumentation and measurement circuits where individual electrical paths may need to be opened during commissioning, maintenance or fault diagnosis.
The addition of two test socket screws further improves serviceability by providing dedicated points for electrical testing. Combined with double compression screw clamps, a compact 6 mm footprint and compatibility with common DIN rail profiles, this makes the M4/6.SNBT.4A a practical solution for organised disconnect and test wiring in industrial panels.
Typical Applications
- Industrial control and automation panels.
- Measurement and instrumentation circuits.
- PLC input and output wiring.
- Signal circuit isolation and testing.
- Commissioning and diagnostic connections.
- Machinery control systems.
- DIN rail test and disconnect terminal assemblies.
