TE Connectivity 1SNA115441R1500 M4/6.SNBT2.V0 is a compact 6 mm screw clamp disconnect terminal block with a blade disconnect and test socket for industrial control, measurement and instrumentation circuits.
£3.75
The TE Connectivity 1SNA115441R1500 is an M4/6.SNBT2.V0 screw clamp disconnect terminal block designed for circuit isolation, testing and measurement in industrial control and instrumentation systems. Part of the established ENTRELEC SNA range, it combines secure screw clamp conductor termination with a blade disconnect and integrated test access.
The M4/6.SNBT2.V0 allows the electrical circuit to be opened at the terminal without removing the connected conductors. This makes it particularly useful during commissioning, maintenance and fault-finding, where individual circuits may need to be isolated quickly while keeping the panel wiring intact and organised.
With a rated conductor cross-section of 4 mm², compact 6 mm spacing and an impulse withstand voltage of 4 kV, the 1SNA115441R1500 provides a robust connection solution for professional panel building. Its polyamide insulating body, UL 94 V-0 flammability classification and wide -55 to +110 °C operating temperature range support dependable use in demanding industrial environments.
Disconnect terminal blocks are valuable in control and instrumentation circuits where individual electrical paths must be isolated during testing, commissioning or maintenance. The M4/6.SNBT2.V0 incorporates a blade disconnect so the circuit can be opened directly at the terminal while the field wiring remains securely terminated.
Integrated test access further simplifies diagnostic work by providing a convenient interface for compatible measurement equipment. Combined with its compact 6 mm profile, screw clamp termination and 4 mm² conductor rating, the ENTRELEC M4/6.SNBT2.V0 is well suited to densely populated industrial control and measurement assemblies.
