The TE Connectivity 1SNA115924R0100, manufacturer designation M10/10.ST1, is a robust screw clamp test and disconnect terminal block designed specifically for current circuit testing, measurement and instrumentation applications. As part of the established TE Connectivity ENTRELEC SNA terminal block series, it enables engineers to perform testing and connect measuring instruments without disturbing the permanently connected field conductors.
The M10/10.ST1 is particularly suited to current transformer (CT) circuits, where safe and convenient access for measurement and testing is essential. Its disconnectable design allows technicians to isolate and test circuits while maintaining organised wiring within the panel, making it a practical solution for metering, protection and industrial electrical systems.
With a 10 mm² IEC nominal cross-section, a 63 V IEC rated voltage and a compact 10 mm terminal width, the 1SNA115924R0100 accommodates solid conductors from 0.5–16 mm² and stranded conductors from 0.5–10 mm². Compatibility with both TS35 and TS32 DIN rails provides flexible installation in new and existing industrial control and measurement panels.
Test and disconnect terminal blocks such as the TE Connectivity M10/10.ST1 provide convenient access to electrical current circuits for measurement, commissioning and maintenance. The terminal allows test equipment and measuring instruments to be connected without disturbing the field wiring, helping technicians perform diagnostic work while maintaining an organised and dependable panel installation.
The M10/10.ST1 is especially useful in current transformer circuits used for electrical metering, monitoring and protection. Its disconnectable construction, screw clamp connections and compatibility with both TS35 and TS32 DIN rails make it suitable for switchgear, distribution panels and industrial measurement systems where accessible current circuit testing is required.
